Product Customer Reviews
Very warm - used in summer A bit bulky for bike bags
It is a product that complies. Indeed, with temperatures lower than those indicated you can get cold, I used it at 3º and if you feel a little cold, it is solved with a set of thermal clothing.
In one word... just fabulous. Extremely comfortable, soft & warm. Fits very well because of the mummy shape of the sleeping bag. Great product.
As described. Used several times over the past 2 years and very good.
Simple and easy to use, high CP value
comfortable
Very nice and comfortable bag, from the description I would have expected it to be more hairy but that's fine.
okay
Very good sleeping bag even if it seems a little expensive for 10°C
Practical and space-saving
I was suffering from hypothermia at the summit of K2 in Parama - Pico Siririca, at the end of December I used this sleeping bag - it saved me, I recommend it!
Worth the purchase! Very comfortable and holds the temperature well
Flimsy zipper
very light and comfortable this bag responds very well to its load, in summer it is perfect, in winter in places with little heating it kept me warm. it is part of my emergency equipment in my car excellent value for money for use in Brittany.
Colour choices needs improvement. MADE IN INDIA products are more preferable

What is the temperature rating?
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.
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 standard
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.
Some advice to consider before you get into your bag
Dress 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.
