Léger et très pratique

Très pratique, léger, compact et confortable. Je recommande


Testé une nuit en bivouac à 2000m dans les Alpes en mai. Nuit entre 0 et 10 degrés. Tient bien chaud (femme de 52kg). Rembourrage au niveau du col pour ne pas laisser passer l'air. Fermetures éclair des 2 côtés. On ne peut pas trouver mieux niveau rapport qualité prix.

à deux détails près

Il manque une poche interne et la système de compression n'est pas top. Voila pourquoi je n'ai pas mis 5 étoiles. Pour ce qui est du reste, ce sdc est excellent, les deux zips sont un vrai plus et les "bourrelets" anti-pont thermique font parfaitement le travail. En comparaison du modèle précédent, il y a une net amélioration.

Chaud et confortable

Avant de l'essayer il vous faudra nettoyer l 'intérieur car le mien était couvert de déchets de garnissage. résultat j' en suis ressorti couvert de garnissage. Il est vraiment large, confortable et suffisamment chaud pour la nuit que j' ai passée dehors sous tente dans un bois. le double zip c'est une super idée. il manque une petite poche en extérieur....

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 according to this measure.

What are the temperatures ratings?

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 28.3", height at the feet 13.4" in size L. Ergonomic hood with drawstring. 2 double-slider side zippers, lined with a flap (tube) in anti-cold fill (thermal bridges), side openings. Easy mechanical ventilation.

Size L 3.7 lbs, user between 5'7" and 6'1". Size L 3.7 lbs, user between 5'7" and 6'1". Folded dimensions: L 16.5" Ø 8.5". Volume 15.2 liters. Size XL 3.9 lbs; user height 6'1" to 6'7".

Weight and size (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.
