All our sleeping bags display the comfort temperatures tested by an independent laboratory (AITEX), in accordance with the international standard ISO 23537-1: 2022.The comfort temperature is the minimum temperature at which an average person (woman, 25 years old, 60kg, 1.60m) is comfortable, without feeling cold, in a relaxed position.Choose your sleeping bag according to this criterion.

The limit temperature is the minimum temperature at which an average person (man, 25 years old, 70kg, 1.73m) can sleep in a curled-up position without feeling cold.And, for your information, the extreme temperature is the minimum temperature at which a person can survive (risk of hypothermia) for 6 hours. This refers to safety, and not comfort.

The protocol for measuring the thermal performance of a sleeping bag is to use a mattress with a thermal resistance corresponding to an R-value of 4.8.If you use a less insulating mattress, the thermal performance of your sleeping bag will be lower.We therefore recommend that you use an insulating mattress for better thermal comfort.

Size S (users up to 1.59m): 670g (incl. 280g of down/feathers) Folded dimensions: L 27cm Ø 15cm. Volume 4.7L Size M (users between 1.60m and 1.69m): 750g (including 322g of down/feathers).

The outer material is made from 100% polyamide in 10 denier (weighing 20g/sqm) and a 30 denier ripstop fabric. This canvas can withstand up to 80,000 abrasion cycles.Durability is calculated using the Martindale test (Standard 12 947-2). This test involves rubbing the bag material against another material to assess the product's abrasion resistance.The inner lining is made from a 100% polyamide fabric in 20 denier, weighing 35g/sqm.

Dress simply (1 layer of clothing, ideally made from merino wool, is enough).Protect your extremities with a hat, gloves, socks and hand warmers if needed.Use a sleeping bag liner to optimise heat and avoid over-washing your sleeping bag Choose a mattress with good insulation (R-value> 3).And an extra tip: contract your muscles (70% of the energy consumed is converted into heat) but do it without moving as this could create a draught!

Even if you regularly use a bag liner, you will need to wash your down bag from time to time. You will find all the relevant information on the Decathlon Sport website.Summary:1/ machine wash, 30°, with 2 or 3 tennis balls. Gentle spin cycle.Use special down detergent (ref: 8609821)2/ Tumble dry with 2 or 3 tennis balls, and repeat 2 or 3 times until completely dry.

On a trek, you can snag a sleeping bag, it happens! The good news is that it can be repaired to prevent the tear from getting bigger or the synthetic fibres from escaping.To do this, we recommend that you use self-adhesive repair patches (ref: 8584596).If you don’t feel comfortable doing this yourself then a heat-bonded patching service is available at the workshop of your Decathlon store.
