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 comfort limit at which a user in relaxed position is in overall thermal balance and is neither hot nor cold (determined for an average woman in normal conditions of use). Choose your sleeping bag according to this criteria.

Limit temperature: temperature limit at which the user of the sleeping bag in huddled-up position is generally in thermal equilibrium and is neither cold nor hot (determined for a standard man under normal conditions of use). We recommend using an insulation mattress to optimise your thermal comfort. This sleeping bag is lined with synthetic wadding to ensure its performance even in wet conditions.

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 (size, fatigue, etc.), equipment (mattress with insulation, etc.), clothing (naked, underwear, etc.) and weather conditions (humidity, wind, etc.).

Dress simply (1 layer of clothing is enough). Warm-up your extremities: 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 converted into heat) but without making any movement generating a cold airstream. Use a sleeping bag liner to maximise the heat and hygiene inside your sleeping bag.

"Generous" mummy shape: wide at the shoulders and tighter at the feet to optimise thermal insulation (no heat loss) and compactness, while maintaining relative freedom of movement. Width at the shoulders 70 cm, height at the feet 32 cm in size L. Ergonomic hood with drawcord. Two side zips with double slider to allow side openings. You can therefore manage the entry of cool air and mechanically ventilate your bag.

Size L 970 g, user height 1.70m to 1.85m. Folded size: L 33 cm Ø 17.5 cm. Volume 7.9 litres. Size XL 1040 g, height between 1.85 and 2.00 m. Folded size: L 33 cm Ø 18.5 cm. Volume 8.9 litres. Volume & dimensions can vary according to the pressure applied to the product.

Volume & dimensions can vary according to the pressure applied to the product. Try your sleeping bag before buying it to choose the right size for your comfort. The advantage of a sarcophagus-shaped sleeping bag is to optimise the weight/volume and thermal ratio. Indeed, with a bag that fits close to the body, you will have less volume to heat (saving your energy). Conversely, this type of bag can limit your freedom of movement, especially when the zips are closed.
