Forclaz 0/5° Ultralight Bivouac/Trekking Sleeping Bag - Orange

We display the comfort temperature ratings on all our sleeping bags. These are tested by an independent laboratory (AITEX) in compliance with European standard EN 13537 of 11/04/2002. The comfort temperature rating is the lowest temperature at which a user in a relaxed position is in thermal equilibrium and feels neither hot nor cold (determined for an average woman in normal conditions of use). Choose your sleeping bag accordingly.

Limit temperature rating: temperature limit at which the user of the sleeping bag in huddled-up position is generally in thermal equilibrium and feels neither cold nor hot (determined for a standard man under normal conditions of use).

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.).

Do not overdress (1 layer of clothing is enough). Warm up your hands and feet: use hats, gloves, socks, bed warmers, rubbing, etc. A flask filled with hot water can be used as a hot water bottle (so long as there's no chance of it opening by accident!) Contract your muscles (70% of the energy consumed is converted into heat) without moving as this could cause a draught of cool air. Use a sleeping bag liner. Ideally, this should be made of silk to maximise the warmth inside your sleeping bag.
