Our designers, who are all outdoor enthusiasts, designed this sleeping bag to sleep comfortably at temperatures of 10oC or above.

What is the temperature rating?We display on all our sleeping bags the comfort temperatures tested by an independent laboratory (AITEX) according to European standard ISO 23537-1 of 21/01/2017. The comfort temperature rating is the lower limit at which the user in relaxed posture is generally in thermal equilibrium and feels neither too cold nor too hot (for a standard woman in normal conditions of use).Choose your sleeping bag according to this criterion.

What is the temperature rating (lower limit at which you feel comfortable)?The comfort limit temperature is the temperature limit at which a person curled up in the sleeping bag is in general thermal equilibrium, neither too cold nor too hot (determined for a man in normal conditions of use).We recommend using an insulation mattress to optimise your thermal comfort.

An important clarification concerning the ISO 23537-1 standardIn the context of this standard, the measurement protocol of a sleeping bag's thermal protection uses a mattress with thermal resistance equal to an R-value of 4.8.This means that by using a less insulating mattress, the thermal performance of your sleeping bag will be lower.We therefore recommend you use an insulating mattress to optimise your thermal comfort.

Some advice to consider before you get into your bagDress simply (1 layer of clothing is enough).Warm-up your extremities: hats, gloves, socks, hand/feet warmers, rubdowns, etc. A flask of hot water can be used as a hot water bottle (as long as there's no chance of it accidentally opening!)Contract your muscles (70% of the energy consumed is converted into heat) but do it without moving as this could create a draught.Use a bag liner to optimise warmth and avoid washing your sleeping bag too frequently.

Want to know more about the wadding?We use 2 overlapping layers of 100% polyester wadding (90% recycled) of 60 g/sqm.It retains its warmth even when wet.

ADDITIONAL SUSTAINABLE DEVELOPMENT INFORMATIONTextile dyeing requires a lot of water but also produces waste water from the dye baths. To reduce this impact on the environment, for the grey fabrics of the sleeping bags, we dye every other yarn in bulk, thereby reducing our water consumption and pollution.This process can reduce CO2 emissions by 19% compared to traditional dyeing methods.In addition, we use a wadding made from 90% recycled polyester
