I use it to make…

I use it to do the Camino de Santiago. It is very light, does not take up much space in the bag. It keeps you warm. Best compact duvet I have.

The storage size is not big, the inner layer is just right when wearing long sleeves and long pants at 15 degrees Celsius, it is very warm.

Lightweight, compact but noisy

Very light and very compact, ideal for transport On the other hand, noisy when creasing and zipper which gets stuck easily

Design

Super light, fits in a small space, warm enough, and easy to pack back. The only thing I don't understand is why it narrows below the knee, since the difference in material would be minimal, but this design slightly worsens the feeling of comfort.

Good sleeping bag for summer

Very compact. I mainly use it in the summer. The format is pleasant, it stores quite easily in its cover. May be a little expensive

Additional Product Information

Composition

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.

Tips before getting 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.
