Au Top !

Je m'en suis servis dans le Désert de Atacama au Chili RAS au Top !

Compact et légzer

Un duvet incroyablement compact pour un poids minimal dans une matière agréable. Ces qualités ne vont pas sans une réduction de l'espace à l'intérieur du sac qui peut ne pas convenir à tout le monde. Il ne reste plus qu'à le tester pour apprécier la thermique annoncée par Forclaz.

Très bon rapport qualité/prix!

Duvet utilisé lors de nuit à 5° et sans être habillé je n'ai pas eu une seul fois eu froid. Semble être de bonne qualité, à voir dans le temps et après plusieurs trek tant attendu en ces jours !

Temperature rating:

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 temperature rating is the lower limit at which the user, in a relaxed pose, is generally in thermal equilibrium and feels neither cold nor hot (for a standard woman in normal conditions of use). Choose your sleeping bag accordingly.

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 feathers and down. This thermal performance can be altered 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 and hygiene inside your sleeping bag.


The mummy shape optimizes thermal insulation (no loss of heat because there is not much air flow or drafts) and saves space, which means that your movements are restricted. Width at the shoulders 28.3", height at the feet 10.2" in size L. Ergonomic hood with drawstring. Double slider, lined with an anti-cold duvet flap, side opening. H-shaped compartment structure to reduce thermal bridges.

Weight and size:

Size S 1.9 lbs, users up to 5'3". Folded dimensions: Ø 6.3" x 13.4". Volume 6.1 Liters. 15.5 oz of feathers. Size M 1.7 lbs, users between 5'3" and 5'7". Folded dimensions: Ø 6.3" x 13.4". Volume 6.9 Liters. 15.5 oz of feathers. Size L 2.2 lbs, height: 5'7" to 6'1". Folded dimensions: Ø 6.7" x 13.4". Volume 7.8 Liters. 1.1 lbs of feathers. Size XL 2.3 lbs, users between 6'1" and 6'7". Folded dimensions: Ø 7.1" x 13.4". Volume 8.7 Liters. 1.2 lbs of feathers.

Size and thermal comfort:

For your comfort, try out your bag before buying it to make sure you have the right size. Ideally, you mustn't reach the end of the bag at the feet or head, nor place the fabric in tension. You will cause thermal bridges that hinder the performance of your sleeping bag. However, if a sleeping bag is too large, it will be harder to heat and will not preserve the body's heat as efficiently.

Origin of feathers:

Thanks to our traceability system, we can guarantee the origin of the feathers, in compliance with our commitment to use responsibly sourced materials. Our suppliers are committed to using only feathers that come from ducks that are bred for their meat and are plucked after slaughtering. The feathers and down used for your sleeping bag come from ducks reared in China.


85% duck down/15% duck feathers. Filling Power of the down: 800 Cuins (IDFB standard) Feathers require special care. Follow care advice.

Washing instructions

Turn inside out and machine wash at 86°F on a delicate cycle with 3 or 4 laundry balls (or clean, used tennis balls). Use a special detergent for feathers and down. Rinse several times. Spin dry on a very slow delicate cycle. Necessary stage: tumble dry on a gentle cycle, at a low temperature. Finish off by air-drying, ideally in the sun, on both sides to prevent the down from clumping together. Dry your sleeping bag thoroughly before storing.
