Gear Review: Salewa – Diadem Warm

salewa diadem-warm schlafsacktest sleeping-bag-review gesamtansicht

The Diadem series from the Italian company Salewa includes three sleeping bag models – Diadem Mild, Diadem, Warm and Diadem Extreme. The comfort temperature range of the sleeping bags ranges from 3°C for the Diadem Mild to -16°C for the Diadem Extreme.

General

The Salewa Diadem Warm is available in two different sizes – Responsive and Long. The Diadem Warm Responsive is suitable for a height of up to 185cm and the Diadem Warm Long up to a height of 195cm. In order to achieve a comfortable temperature of -2 ° C, Salewa decided on a 500g down filling with a mixed ratio of 90/10 duck down. In addition, the down filling has a minimum fill power of 750cuin.

Size  
     Responsive Height up to 185cm
     Long Height up to 195cm
Zipper Left or right
Weight without bag 1092g
Weight with bag 1163g
Packing Size 28 x 22 x 20cm
Price ca. 400 EUR

 

Due to the good down mix ratio and the high minimum filling power, the Diadem Warm can be used up to an extreme temperature of -26 ° C. The Salewa Diadem Warm weighs 1092g.

Special Details

Salewa achieves the high thermal output of the Diadem Warm in addition to the high-quality down filling with a special chamber system. Furthermore, Salewa has provided the sleeping bag with an insulated cover strip and a pre-formed thermal hood, which should prevent warm air from escaping from the sleeping bag through movement. Another detail of the Diadem Warm is the inside pocket, which allows you to keep your valuables close to you even at night.

Review

In order to test the thermal output of the Salewa Diadem Warm, we warmed up the sleeping bag and used a thermal imaging camera to see how much heat the sleeping bag emits and where cold bridges occur. First, we spread out the sleeping bag so that the down can be puffed up properly and maximum isolation can be achieved. To warm up the sleeping bag, we placed three hot water bottles, which we filled with hot water, in the body area of the sleeping bag, as well as a hot water bottle in the head area. We put two glasses between the hot water bottles so that the warm air can be distributed throughout the sleeping bag.

After 15 minutes we took three pictures with the thermal imaging camera in order to see in which areas the Salewa Diadem Warm emits the most heat. The blue areas on the pictures mean that they have the lowest surface temperature and the further the color changes towards red, the higher the surface temperature at these points is. However, the images cannot be compared one-to-one, as the temperature range is redefined for each image. You can see this from the three temperature indications on the picture (red = highest temperature, green = lowest temperature, white = average temperature). The three small red areas that can be seen on the overall view are only in those areas where the sleeping bag is exposed to the greatest heat. Below the opening of the head, the red area is only in folds, where the heat can easily accumulate. You can see this very well on the close-up of the head area. The close-up of the head area also shows that the Salewa Diadem Warm has weaknesses in terms of insulation there. In the two close-ups it is also easy to see that the sleeping bag is very well insulated in the area of the zipper and that no additional heat escapes through it.

Conclusion

The Salewa Diadem Warm is right in the middle between the perfect touring sleeping bag for the winter and the winter sleeping bag, where weight and pack size are irrelevant. On the one hand, it is one of the lighter sleeping bags but on the other hand, the packing size is more in the larger area. The same picture emerges with the thermal insulation and the price, here too the Diadem Warm is right in the middle if you compare it with other sleeping bags.

Gear Review: Nordisk Passion Five

nordisk yeti passion-five schlafsacktest gear-review sleeping-bag gesamtansicht

The Passion Five is the warmest sleeping bag in the three-part premium sleeping bag series from the Danish manufacturer Nordisk. The comfort temperatures of the Passion series range from 15 ° C for the Passion One to over 7 ° C for the Passion Three and down to -2 ° C for the Passion Five.

General

The Passion Five is currently available in three different sizes. The smallest size is M, which is suitable for people up to 175cm. For taller people, Nordisk has the sizes L and XL, whereby the manufacturer limits size XL to a maximum height of 205cm. In addition to the different sizes, the Passion Five is also available in three different colors – Mood Indigo / Black, Navy / Black and Brown / Black. Nordisk however does not offer a choice of zipper side. The different models are all only available with the zipper on the left side.

The Passion Five has a comfort temperature of -2°C, but according to the EN13537 test it can be used up to an extreme temperature of -25°C.

Size
     M Height up to 175cm
     L Height up to 190cm
     XL Height up to 205cm
Zipper Left
Weight without bag 788g
Weight with bag 812g
Packing Size 37×14 cm
Price ca. 643 EUR

The Nordisk Passion Five is an absolute lightweight with a weight of only 788g without pack sack and 812g including packing sack. And even with the packing size of only 37x14cm, the Passion Five can even keep up with summer sleeping bags. In order to guarantee the highest possible thermal output, Nordisk uses 100% goose down with a mix ratio of 95/5 and a fill power of 800 cuin for the Passion Five. Both the mixing ratio and the fill power are absolute top values when compared to other winter sleeping bags.

Special Details

Thanks to the S-chamber construction of the Passion Fives, Nordisk achieves particularly good heat output on the sensitive sleeping bag sides. Another advantage is that the S-chamber construction does not add any additional weight and that with improved thermal performance. In order to ensure the greatest possible sleeping comfort, Nordisk uses a mummie shape for the Passion Five, which touches the contour of the human body and therefore converges more closely in the foot area. This reduces the air in the sleeping bag and therefore less air has to be heated with the body heat.

An additional warming collar should prevent warm air from escaping through the head opening from the sleeping bag. The hood is therefore equipped with a drawstring to further reduce the escape of warm air.

Review

In order to test the thermal output of the Nordisk Passion Five, we warmed up the sleeping bag and used a thermal imaging camera to see how much heat the sleeping bag emits and where cold bridges occur.

First, we spread out the sleeping bag so that the down can be puffed up properly and maximum isolation can be achieved. To warm up the sleeping bag, we placed three hot water bottles, which we filled with hot water, in the body area of the sleeping bag, as well as a hot water bottle in the head area. We put two glasses between the hot water bottles so that the warm air can be distributed throughout the sleeping bag.

After 15 minutes we took three pictures with the thermal imaging camera in order to see in which areas the Nordisk Passion Five emits the most heat. The blue areas on the pictures mean that they have the lowest surface temperature and the further the color changes towards red, the higher the surface temperature at these points is. However, the images cannot be compared one-to-one, as the temperature range is redefined for each image. You can see this from the three temperature indications on the picture (red = highest temperature, green = lowest temperature, white = average temperature).

As expected, the Nordisk Passion Five shows the greatest heat emission in the areas in which the hot water bottles were placed, as this is where the sleeping bag is exposed to the greatest heat. You can clearly see this on the overall view by the three red spots. The detailed photo of the foot area shows that the sleeping bag emits more heat on the left than on the right. But overall has a great isolation.

Conclusion

The low weight and the small pack size make the Passion Five the perfect companion for multi-day tours. On top of that, you don’t have to compromise on the warmth of the sleeping bag. On the other hand, this comes at a price. In summary, it can be said that the Nordisk Passion Five is an absolute premium sleeping bag for everyone who is planning long tours with overnight stays outside in colder temperatures.

Gear Review: Mountain Hardwear Rock™ 15F/-9C

Mountain-Hardwear Rock-15F/-9C schlafsacktest gear-review sleeping-bag gesamtansicht

The Rook™ series is a series of three sleeping bags from the American outdoor manufacturer Mountain Hardwear. The temperature limits of the three sleeping bags range from -1°C to -18°C. All three sleeping bags are available in a unisex version and a women’s version. Here in the test, we tested the unisex version.

General

The Mountain Hardwear Rook ™ 15F/-9C is available in two different sizes. The unisex version is divided into two versions. The Regular version is for people with a maximum height of 183cm and the long version for people with a height of up to 198cm. With both versions, the zipper is optionally available on the left or right side.

Size
     Regular Height up to 183cm
     Long Height up to 198cm
Zipper Links oder rechts
Weight without bag 1.084 g
Weight with bag 1.215 g
Packing Size 39 x 20 cm
Price Ca. 290 EUR

During our online research, we came across different weight information. According to the manufacturer, the Mountain Hardwear Rock™ 15F/-9C has a weight of around 1092g. However, the online shop gives the weight as 1125g. We weighed it again and the result was a weight of 1215g including the packing bag. Mountain Hardwear uses an 80/20 mix of down and feathers with a fill power of 650 cuin. The filling weight is about 600g.

Special Details

The Rook ™ 15F / -9C is equipped with a very special thermal collar, as this is not located inside the sleeping bag, but goes around the head opening. This is to prevent cold air from getting into the sleeping bag. In addition, the sleeping bag also has an additional thermal collar, which prevents any cold air from the head area from reaching the lower area of the sleeping bag.

The outer material chosen by Mountain Hardwear is water-repellent, which means that the Rook ™ 15F / -9C can also be used for bivouacking, as the sleeping bag is hereby often covered with dew in the spring and autumn.

Review

In order to test the thermal output of the Mountain Hardwear Rook™ 15F/-9C, we warmed up the sleeping bag and used a thermal imaging camera to see how much heat the sleeping bag emits and where cold bridges occur.

First, we spread out the sleeping bag so that the down can be puffed up properly and maximum isolation can be achieved. To warm up the sleeping bag, we placed three hot water bottles, which we filled with hot water, in the body area of the sleeping bag, as well as a hot water bottle in the head area. We put two glasses between the hot water bottles so that the warm air can be distributed throughout the sleeping bag.

After 15 minutes we took three pictures with the thermal imaging camera in order to see in which areas the Mountain Hardwear Rook™ 15F/-9C emits the most heat. The blue areas on the pictures mean that they have the lowest surface temperature and the further the color changes towards red, the higher the surface temperature at these points is. However, the images cannot be compared one-to-one, as the temperature range is redefined for each image. You can see this from the three temperature indications on the picture (red = highest temperature, green = lowest temperature, white = average temperature).

The overall view of the Mountain Hardwear Rock™ 15F/-9C shows a surface temperature of 10.8 ° C in the middle of the sleeping bag. This is approx. 2 ° C higher than with comparable sleeping bags. One reason for this could be, for example, the low fill power (650cuin) of the down used. Furthermore, two particularly heat-permeable areas are noticeable in the overall view. It should be noted here, however, that these areas were exposed to a particularly high amount of heat during the test. The area in the middle of the sleeping bag that was exposed to the same heat does not show this heat release. From this it can be concluded that the Rook ™ 15F/-9C is better lined in the middle section than in the foot and upper area. In the close-up of the head area, it can be seen that heat emits here both via the seams and the surfaces.

Conclusion

The Rook™ 15F/-9C shows a few weak points in the thermal heat test but is generally a very solid winter sleeping bag. Personally, we were not the convinced by the material that Mountain Hardwear uses, because in our opinion it is not particularly pleasant on the skin and does not feel very cosy.

In summary, one can say that the Mountain Hardwear Rook ™ 15F/-9C is a good winter sleeping bag for all those who focus on price and not packing size and weight.

Gear Review: Mammut Sphere Down 3-Season

mammut sphere-down-3-season schlaftsacktest gear-review sleeping bag blau

The Sphere Down 3-Season is a down sleeping bag from the Swiss company Mammut and one of seven different down sleeping bags that Mammut currently offers.

General

The Sphere Down 3-Season is available in two different versions. One variant for a height of up to 180cm and the second variant for people with a height of up to 195cm. The Shpere Down 3-Season is currently not available as a women’s version.

The comfort temperature of the sleeping bag is -1°C and according to the manufacturer, the sleeping bag can be used till temperatures low as -24°C.

Size
    185 Height up to 185cm
    195 Height up to 195cm
Zipper Left
Weight without bag 826g
Weight with bag 906g
Packing Size
Price ca. 530 EUR

Mammut uses 90% goose down and 10% goose feathers as filling for its Sphere Down 3-Season, both of which are certified with the RDS (Responsible Down Standard). According to the manufacturer, the total filling weight is 450g and the total weight of the sleeping bag without pack sack is 826g. At 826g, the Sphere Down 3-Season is definitely one of the lightweights among the three-season sleeping bags.

Special Details

The main feature of the Shpere Down 3-Season is the feather-light outer fabric made of prolightTX ™, which, according to alpin.de, weighs only 330g. In order to keep the total weight of the sleeping bag as low as possible, Mammut does without a thermal collar. Heat collars are used in many sleeping bags to prevent cold air from entering the body part of the sleeping bag. In the foot area, Mammut uses additional insulation to provide more sleeping comfort and prevent cold feet. Mammut relies on wave-shaped chambers so that the down in the sleeping bag does not slip and cold bridges are avoided.

Review

In order to test the thermal output of the Mammut Sphere Down 3-Season, we warmed up the sleeping bag and used a thermal imaging camera to see how much heat the sleeping bag emits and where cold bridges occur.

First, we spread out the sleeping bag so that the down can be puffed up properly and maximum isolation can be achieved. To warm up the sleeping bag, we placed three hot water bottles, which we filled with hot water, in the body area of the sleeping bag, as well as a hot water bottle in the head area. We put two glasses between the hot water bottles so that the warm air can be distributed throughout the sleeping bag.

After 15 minutes we took three pictures with the thermal imaging camera in order to see in which areas the Mammut Sphere Down 3-Season emits the most heat. The blue areas on the pictures mean that they have the lowest surface temperature and the further the color changes towards red, the higher the surface temperature at these points is. However, the images cannot be compared one-to-one, as the temperature range is redefined for each image. You can see this from the three temperature indications on the picture (red = highest temperature, green = lowest temperature, white = average temperature).

The thermal image with the overall view of the sleeping bag shows that the Sphere Down 3-Season does not show any clear weak points in terms of thermal output. A close-up view of the foot area shows that the seams give off more heat than the other areas. But this is not a surprise, as the down filling is steaming at the seams. Both in the general view and in the close-up of the head area, slight weak points can be seen in the thermal insulation of the zipper.

Conclusion

The Mammut Sphere Down 3-Season is a very light three-season sleeping bag that can keep up with pure winter sleeping bags in terms of thermal insulation. However, the low weight ensures that the thermal insulation has slight weaknesses in certain places. Despite this, the low weight and the small pack size make the Sphere Down 3-Season a perfect companion for hiking and trekking tours in cold temperatures.

Gear Review: Grüezi Bag – Biopod DownWool Ice 185

grüezi-bag biopod-downwool-ice-185 schlaftsacktest gear-review gesamtansicht blau

The Biopod DownWool Ice 185 is one of three sleeping bags in the Ice sleeping bag series from the German company Grüezi Bag. The comfort temperature of the sleeping bags range ranges from -1°C for the Ice to -8°C for the Ice Extreme. In our test we tested the Biopod DownWool Ice 185.

General

The DownWool Ice 185 is currently available in three different sizes. The maximum body size for the sleeping bag can be found in the name of the sleeping bag. In this case of the DownWool Ice 185 it is 185cm accordingly. The comfort temperature is -1 ° C. According to EN 13537 temperature specifications, the sleeping bag can be use till temperature of -26 ° C.

Size
     175 Height up to 175cm
     185 Height up to 185cm
     200 Height up to 200cm
Zipper Rechts
Weight without bag 1612g
Weight with bag 1708g
Packing Size (uncompressed/ compressed) Ø 22 x 38 cm/ Ø 23 x 25 cm
Price ca. 438 EUR

Grüezi Bag reaches a comfort temperature of -1 ° C with 750g of its unique down-wool mixture of 70% duck down and 30% refined wool. The duck down filling used has a 90/10 down-feather ratio with a filling power of 650cuin. The down used by Grüezi Bag is also certified with the Resposible Down Standard (RDS). The compressed packing size of the sleeping bag is Ø 23 x 25 cm with a weight of 1708g.

Special Details

To prevent cold air from escaping from the sleeping bag, Grüezi Bag has equipped the DownWool Ice 185 with a warmth collar, an adjustable hood and a face baffle. In addition, the sleeping bag can be equipped with an electrically heated hip bag. However, this is not included in the purchase price. For the highest possible sleeping comfort, the sleeping bag has a pillow compartment, which prevents the pillow from slipping.

For the outer material, Grüezi Bag relies on the highly water-repellent impregnation Bionic Finish Eco. Furthermore, the sleeping bag is equipped with an inner pocket and an outer pocket, which allow you to stow your valuables close to you.

Review

In order to test the thermal output of the Grüezi Bag Biopod DownWool Ice 185, we warmed up the sleeping bag and used a thermal imaging camera to see how much heat the sleeping bag emits and where cold bridges occur.

First, we spread out the sleeping bag so that the down can be puffed up properly and maximum isolation can be achieved. To warm up the sleeping bag, we placed three hot water bottles, which we filled with hot water, in the body area of the sleeping bag, as well as a hot water bottle in the head area. We put two glasses between the hot water bottles so that the warm air can be distributed throughout the sleeping bag.

After 15 minutes we took three pictures with the thermal imaging camera in order to see in which areas the Grüezi Bag Biopod DownWool Ice 185 emits the most heat. The blue areas on the pictures mean that they have the lowest surface temperature and the further the color changes towards red, the higher the surface temperature at these points is. However, the images cannot be compared one-to-one, as the temperature range is redefined for each image. You can see this from the three temperature indications on the picture (red = highest temperature, green = lowest temperature, white = average temperature).

In the overall view it can be clearly seen that the Grüezi Bag Biopod DownWool Ice 185 emits a lot of heat at the points where the hot water bottles are placed. But this is normal because here the sleeping bag is exposed to enormous heat. Furthermore, the thermal imaging camera shows that the sleeping bag is well insulated. This can also be clearly seen in the close-ups of the foot and head area. In the head area, slight discoloration / loss of heat can be seen at the seams.

Conclusion

The Grüezi Bag is the only company that uses a mixture of down and wool. The images from the thermal imaging camera clearly show that Grüezi Bag can keep up with other sleeping bags in terms of thermal performance. Otherwise, the Biopod DownWool Ice 185 feels very high in quality. Only the very high weight and the large pack size are reasons for us why the Biopod DownWool Ice 185 should not be included on every winter tour.

Gear Review: Deuter Astro Pro 800

deuter astro-pro-800 astro schlaftsacktest gear-review gesamtansicht blau

With the Astro Pro sleeping bag series, Deuter has launched a sleeping bag series that includes four sleeping bag models. The four sleeping bag models differ mainly in the temperature range and thus also in the areas of applications and the comfort temperature ranges of the Astro Pro series range from 2°C for the Astro Pro 400 to -12°C for the Astro Pro 1000. The Astro Pro 400, 600 and 800 models are also available in a women’s version.

General

The Deuter Astro Pro 800 is available in three different sizes – Regular, L & SL (women). The regular version is suitable for people with a height of up to 185 cm, the L version for people with a height of up to 200 cm and the SL variant is the female model and is suitable up to a height of 175cm. The female model is specially adapted to the need of women in which reinforcing inserts in the kidney and foot area were used for a higher comfort.

Deuter’s Astro Pro 800 has a comfort temperature of -7°C, a transition temperature of -15°C and an extreme temperature of -33 ° C. This temperature range classifies the Astro Pro 800 as a classic three-season sleeping bag, although people who are sensitive to the cold can also use the sleeping bag on very mild summer nights.

Size  
   Regular Height up to 185cm
   L Height up to 200cm
   SL (Woman) Height up to 175cm
Zipper Left
Weight without bag 1410g
Weight with bag 1520g
Packing Size ø 19 cm x 41 cm
Price ca. 370 EUR

The Astro Pro 800 has a filling weight of 800g, which is what the 800 stands for in the product name. The total weight of the sleeping bag is 1410g without packsack and 1520g with packsack, which means that the Astro Pro 800 is not an absolute lightweight but is absolutely within the range of similar products with the same comfort temperature. Deuter filled the Astro Pro 800 with a 90/10 down/ feather blend with a fill power of 650+ cuin.

Special Details

Deuter has equipped the Astro Pro 800 with a Stretch Comfort System, which means that the sleeping bag can be stretched by up to 25% in width and thus ideally adapts to the body shape. The waffle structure of the down chambers in the lower area of the sleeping bag prevents the downs from slipping when moving at night and thus always ensures ideal thermal insulation. In addition, the Astro Pro 800 has a thermal collar that is designed to prevent cold air from entering the sleeping bag. This is secured with Velcro so that the thermal collar does not move or open while sleeping. The sleeping bag also has a pocket inside the sleeping bag.

The included compression bag allows an easy and very compressed packing, which is very practical, especially on longer trekking tours, as the space in the backpack is known to be limited.

Review

In order to test the thermal output of the Deuter Astro Pro 800, we warmed up the sleeping bag and used a thermal imaging camera to see how much heat the sleeping bag emits and where cold bridges occur.

First, we spread out the sleeping bag so that the down can be puffed up properly and maximum isolation can be achieved. To warm up the sleeping bag, we placed three hot water bottles, which we filled with hot water, in the body area of the sleeping bag, as well as a hot water bottle in the head area. We put two glasses between the hot water bottles so that the warm air can be distributed throughout the sleeping bag.

After 15 minutes we took three pictures with the thermal imaging camera in order to see in which areas the Deuter Astro Pro 800 emits the most heat. The blue areas on the pictures mean that they have the lowest surface temperature and the further the color changes towards red, the higher the surface temperature at these points is. However, the images cannot be compared one-to-one, as the temperature range is redefined for each image. You can see this from the three temperature indications on the picture (red = highest temperature, green = lowest temperature, white = average temperature).

The images from the thermal imaging camera show that the Deuter Astro Pro 800 has good thermal insulation, as the surface in the middle of the sleeping bag has only risen to 6.4 ° C. However, it is noticeable that a relatively large amount of heat emits in the folds and seams of the foot area. However, this is not visible in the head area, which is very important when the sleeping bag is used on the edge of the comfort area.

Conclusion

The Deuter Astro Pro 800 is a great sleeping bag for an overnight stay outdoors in minus degrees. Due to the high weight and the relatively large pack size, the Astro Pro 800 is not suitable for longer winter tours, where you have to pay close attention to the weight. On the other hand, the Astro Pro 800 can also be classified in the lower price segment for winter sleeping bags.

Gear Review: Mountain Equipment CLASSIC 750 – Women

mountain-equipment classic-750 frau schlaftsacktest gear-review test gesamtansicht blau

The Classic 750 sleeping bag is part of the Classic series comprising four sleeping bags from the American company Mountain Equipment. Comfort ranges of the models range between 5 ° C for the Classic 300 and -9 ° C for the Classic 1000. The sleeping bags of the Classic series are all available in a unisex version and a women’s version. In our test, we tested the women’s version of the Classic 750 for you.

General

The Mountain Equipment Classic 750 – Women is available in two sizes, Regular and XL. The regular size is suitable for people with a height of up to 170 cm and the XL version up to a height of 185 cm. In addition, both models offer the choice on which side the zipper should be.

The comfort temperature of the Classic 750 is -5°C and according to EN 13537 temperature specifications, the sleeping bag can even be used in temperatures low as -31°C, which makes it perfect for use on nights when temperatures can sometimes drop below freezing point.

 

Size
     Regular Height up to 170cm
     XL Height up to 185cm
Zipper Left or right
Weight without bag 1265g (nachgewogen)
Weight with bag
Packing Size 28 x 22 x 20cm
Price 370,37 EUR

 

With a weight of 1265g including the bag and a pack size of 28 x 22 x 20cm, the Classic 750 is very well suited for longer tours during the cold seasons.

Special Details

To ensure the best possible heat output, the Classic 750 is equipped with sloping box chambers. The sloping boxing chambers also reduce the weight. Furthermore, Mountain Equipment relies on their Lode Lock System, a magnetic closure, to close the thermal collar, which is supposed to prevent unintentional opening. As a further warming feature, Mountain Equipment uses five chambers in the head area, which hold the down filling in place, and two down chambers with generous volume in the foot area.

In addition, Mountain Equipment uses Helium 40 as the outer material for the Classic 750, which makes the outer layer of the sleeping bag water-repellent and windproof from the outside. The down filling is made from 90% duck down.

Review

In order to test the thermal output of the Mountain Equipment Classis 750 – Women, we warmed up the sleeping bag and used a thermal imaging camera to see how much heat the sleeping bag emits and where cold bridges occur.

First, we spread out the sleeping bag so that the down can be puffed up properly and maximum isolation can be achieved. To warm up the sleeping bag, we placed three hot water bottles, which we filled with hot water, in the body area of the sleeping bag, as well as a hot water bottle in the head area. We put two glasses between the hot water bottles so that the warm air can be distributed throughout the sleeping bag.

After 15 minutes we took three pictures with the thermal imaging camera in order to see in which areas the Mountain Equipment Classis 750 – Women emits the most heat. The blue areas on the pictures mean that they have the lowest surface temperature and the further the color changes towards red, the higher the surface temperature at these points is. However, the images cannot be compared one-to-one, as the temperature range is redefined for each image. You can see this from the three temperature indications on the picture (red = highest temperature, green = lowest temperature, white = average temperature).

 

The three images of the thermal imaging camera show that the Mountain Equipment Classic 750 has no unusual weak points in terms of thermal insulation. What is particularly striking is the very good insulation of the hood, where hardly any heat emission can be seen. Here it seems as if the seams are extra insulated again, as weak points can be seen in the foot area.

 

Conclusion

The Classic 750 from Mountain Equipment is an excellent sleeping bag for the colder seasons, but also in summer, when travelling to colder regions, the Classic 750 is the ideal companion for people who freeze more easily at night or who like it especially warmer. Only the rather large pack size and the rather high weight make the Classic 750 not an ideal companion for longer tours during the cold season. In return, the Classic 750 is convincing in terms of price
