Ergonomic hood with drawcord.2-Way YKK zip, with anti-pinch system for optimal ventilation.A baffle along the zip prevents heat loss.Inner zipped pocket.2 Buckles at the base of the bag so you can hang it up and dry it.Comes with a perforated fabric storage bag.

The outer material is made from 100% polyamide in 10 denier (weighing 20g/m2) and a 30 denier ripstop fabric. This canvas can withstand up to 80,000 abrasion cycles.robustness 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 35 g/m2.

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.

All our sleeping bags display the temperature ratings, tested by an independent laboratory (AITEX), in accordance with the European standard NF ISO 23537 - 1:2022.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.

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).

In 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.
