    Good sleeping back

    It's small and light, so perfect for a trip where size and weight of luggage is crucial.
    Suggestions for Improvements:
    - The zippers should go all the way down and not end at knee-height
    - The zipper was sometimes really difficult to open
    - A pocket inside the sleeping bag would be handy to keep personal belongings close

Use temperature:
We label all of our sleeping bags with a "comfort temperature" which is tested by an independent laboratory (AITEX) in accordance with European standard EN 13537 of 11/04/2002. The "comfort temperature" is the lower temperature limit at which the user feels comfortable overall - neither hot nor cold - while lying in a relaxed position (temperature determined for an average woman under normal conditions of use). Choose your sleeping bag accordingly.
What are the temperature "limits" at which it can be used?
Comfort limit temperature: The minimum temperature at which a user feels comfortable overall - neither hot nor cold - while huddled up in the sleeping bag (as determined for an average male user under normal conditions).
However, here's what you need to know about temperatures:
A sleeping bag does not produce any heat. Rather, it retains the heat produced by the body. If you are tired and cold and you slip inside a cold, damp sleeping bag, you will most likely feel cold no matter how good your bag! These temperatures depend on a person's ability to withstand cold (build, fatigue, etc.), his equipment (insulating mattress, etc.), the way he is dressed (if he is naked, wearing underwear, etc.), and weather conditions (damp, wind, etc.).
For greater comfort, before getting into your sleeping bag:
Dress simply (1 layer of clothing is enough). Keep your extremities warm: use hats, gloves, socks, bed warmers, rubbing, etc. A flask filled with hot water can be used as a foot or bed warmer (so long as there's no chance of it opening by accident!) Contract your muscles (70% of the energy you consume is transformed into heat) without making movements that could cause a draught. Use a sleeping bag sheet, ideally made from silk.
