Perfect for hiking

Very light and compact sleeping bag, which keeps you warm even when sleeping under the stars in the high mountains in summer (July/August). Also tested and approved in the high mountains in September, with a few extra layers of clothing.

Very convenient

Very practical to carry, but really tiny once forgotten in the pouch

Excellent!

Lightweight, comfortable down sleeping bag. Super pack size. Temperature data match. As a side sleeper you have enough space for your arms, even when the sleeping bag is completely closed. All in all very recommendable!

Specified temperatures and weight for size XL are correct, small pack size, good workmanship. Great value for money! Would I buy again.

I recommend it, because of the size and speed of packaging

Super packing and handling, small size for carrying and roomy inside. Very pleasantly surprised!!! I recommend...

great compact sleeping bag

Nice sleeping bag to sleep in also fits nicely. Compact to transport in its compression bag. I have not really been able to test the operating temperature because it was much warmer than the indicated 10 degrees.

Super cozy

I've been thinking about buying it for sooo long. Actually, I never wanted a down sleeping bag and I don't like mummy shape at all. Now I bought the sleeping bag because of the pack size. I'm 167 and bought the size L. I like the size. In width it is 80cm. The width is different in the description. The width is great. I sleep on my side and was able to put my arms on my side. It doesn't rustle so loudly and feels soft and cuddly. The hood can also be used as a mini pillow. It was about 14 degrees at night. Wasn't cold or too warm. At 10 degrees I would of course dress warmer or take a fleece blanket with me. Then it will definitely go lower with the temperature. I love him and I don't regret it.

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. 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).

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.

Style

The mummy shape optimises thermal insulation (no loss of heat because there is not much air flow or draughts) and saves space, which means that your movements are restricted.Width at the shoulders 73 cm, height at the feet 27 cm in size L.

The advantages of a duck down and feather filling

The filling power of down has 3 advantages for mountain sports:- Thermal insulation thanks to the air trapped in the down and feathers- Ultra low weight: down is lighter than synthetic wadding while offering the same degree of warmth. This saves even more weight in your backpack- Ultra-compressible

How to measure the fill power of a down and feather wadding?

The fill power is a measure of the down's thermal insulation capacity and its potential to ”trap” air. It is expressed in CUIN (cubic inches).So, down with a higher fill power (higher CUIN number) will occupy more space, trap more air and provide greater thermal insulation.For this sleeping bag with its 90% down / 10% feathers filling, the fill power is guaranteed to be 800 CUIN or more (international IDFB standard).

Storage instructions

To maintain its fill power, which is necessary for its insulation properties, store your sleeping bag by stuffing it in the mesh bag provided, feet first. Can be stored flat.
