Very Good Product

the product was very good warm comfortable, the XL size which i picked so i can move inside comfortably. haven't use the product in very low temperature.. while opening zips sometime outer material stuck in that zip...

Not warm enough

The rating of 10 I was told meant you could technically sleep without clothes inside and be comfortable in 10deg. I put this to the test and it is not true. I had 3 layers of clothes on and the sleeping bag is like paper. So thin and doesn’t keep you warm at all. My son was very comfortable and warm in his $20 Aldi sleeping bag though.

Very nice

Muy bueno

Lo he utilizado en tienda de campaña con temperatura exterior de -1 y -2 grados y no he pasado frío, mido 1,85 y peso 85 kg, recomendable

icon-circle-checkmark verified purchase

Lo utilizo en mis salidas con tienda de campaña, en verano y en otoño, aunque creo que también lo podré usar en invierno ya que es muy cálido. En cuanto a su peso, es muy ligero y me gusta que se pueda compactar para poder llevarlo fácilmente en la mochila. Muy satisfecho.

Muy caliente y comodo. Y facil de guardar.

Facil de guardar, y caliente. Es muy comodo y va perfecto para acampar.

Cette forme sarcophage n’est pas très confortable mais par contre prend moins de place dans un sac à dos et est un peu moins lourd.

Use temperature

All our sleeping bags display the temperature ratings, tested by an independent laboratory (AITEX), in accordance with the European NF ISO 23537 standard (2017). The comfort temperature is the lower limit at which the user, in a relaxed pose, is in overall thermal equilibrium and feels neither too cold nor too hot (for a standard woman in normal conditions of use). Choose your sleeping bag accordingly.

What are the "limit" temperatures for use?

Limit temperature: temperature at which the user huddled up in the sleeping bag is generally in thermal equilibrium and feels neither too cold nor too hot (defined for a standard man and in normal conditions of use). We recommend you use an insulating mattress to optimize your thermal comfort. This sleeping bag is filled with synthetic fill to guarantee performance even in damp conditions.

What you need to know about temperatures

A sleeping bag does not produce heat but retains the heat produced by the body. If you are tired and cold and you slip inside a cold, damp sleeping bag, it is very likely that you will feel cold no matter how good your sleeping bag is! These temperatures therefore depend on the person's resistance to cold (bulk, fatigue, etc.), equipment (mattress with insulation, etc.), clothing (naked, underwear, etc.) and weather conditions (humidity, wind, etc.).

For greater comfort, before getting into your sleeping bag

Dress simply (1 layer of clothing is enough). Keep your head, hands and feet warm: use hats, gloves, socks, bed warmers, rubbing, etc. A flask filled with hot water can be used as a hot water bottle (if it can't open by accident !) Contract your muscles (70% of the energy consumed is transformed into heat). However you should do this without moving as this can cause drafts of cold air. Use a sleeping bag liner to maximize the heat inside your sleeping bag.


"Generous" mummy shape: wide at the shoulders and tighter around the feet to optimize thermal insulation (no loss of heat) and remain compact, while keeping relative freedom of movement. Width at the shoulders 27.6", height at the feet 12.6" in size L. Ergonomic hood with drawstring. 2 side zippers with 2-way slides to open on the side. You can also manage cool air entry and ventilate your bag mechanically.

Weight and dimensions

Size S 1.7 lbs, users up to 5'3". Folded dimensions: L 13" Ø 6.1". Volume 6.2 Liters. Size M 2 lbs, users between 5'3" and 5'7". Folded dimensions: L 13" Ø 6.5". Volume 7.1 Liters. Size L 2.1 lbs, users between 5'7" and 6'1". Folded dimensions: L 13" Ø 6.9". Volume 7.9 Liters. Size XL 2.3 lbs, users between 6'1" and 6'7". Folded dimensions: L 13" Ø 7.3". Volume 8.9 Liters. Volume and dimensions can vary according to the pressure applied to the product.

Weight and dimensions (2):

Volume and dimensions can vary according to the pressure applied to the product.For your comfort, try out your bag before buying it to make sure you have the right size. The advantage of a mummy-type sleeping bag is that the weight/volume ratio and thermal comfort are optimized. With a fitted bag, there is less volume to heat (saves your energy). However, this type of sleeping bag can limit your freedom of movement, especially when the zippers are closed.


This sleeping bag is guaranteed for 5 years from the date shown on the sales receipt. The product covered by the warranty will be repaired or exchanged free of charge. The warranty covers product defects, excluding those resulting from normal wear and tear and improper use. This special 5-year warranty is only valid on presentation of the product and receipt.



Product testing

All our sleeping bags undergo mechanical tests that test the performance and resistance of the sleeping bag to guarantee better sleep and recuperation (thermal resistance, resistance to abrasion, comfort, etc). We also carry out many tests in the field, in real conditions.

Storage instructions

Easily store your bag by stuffing it in its bag, feet end first. To maintain its fill power, which is what provides the thermal insulation, remove the bag and store it flat in a dry place.
