Trekking Sleeping Bag - TREK 500 5° - Burgundy

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.

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 optimise your thermal comfort.This sleeping bag is made with synthetic wadding to perform even in humid 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 (bulk, 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).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 draughts of cold air.Use a bag liner to maximise the heat and hygiene inside your sleeping bag.

"Generous" mummy shape: wide at the shoulders and tapered at the feet allows optimum thermal insulation (no heat loss) and compactness while keeping a certain freedom of movement.Shoulder width 70 cm, height at the feet 32 cm in size L.Ergonomic hood with drawcord.Two two-way side zips allows for side openings. You can therefore manage the cool air flow and mechanically ventilate your sleeping bag.

Volume & dimensions can vary according to the pressure applied to the product.Try out your sleeping bag before buying it to make sure you have the right size & you are comfortable. The advantage of a mummy-shaped sleeping bag is to optimise the weight/volume ratio and heat. Basically, with a sleeping bag close to your body you have less volume to heat (saving your energy). On the other hand, this type of sleeping bag can restrict your freedom of movement, particularly when the zips are closed.
