Down for bivouac

Purchased for our children. A little big at the moment by choice (seeing how they grow), looks very warm. Compact, lightweight.

A top quality sleeping bag.

A somewhat (too) heavy sleeping bag for walking, but doable, just put a little less luggage in the backpack....

HIGH PERFORMANCE SLEEPING BAG EVEN AT LOW TEMPERATURES. I HIGHLY RECOMMEND

The quality of sleeping bag is not good and not good for 4 c or below

A sleeping bag not up to the indicated temperature

Even with a Damart high and low... If it's 0°... I don't have a good night's sleep in this duvet. Very disappointed. I bought it for a 2 month trip through the Middle East where the nights are cold. Well I was cold. And you absolutely have to wear socks too, otherwise your feet will be frozen. From 5° it becomes limiting. And to answer the insulation argument... I sleep on a 5cm mattress in my car. So I don't think that's a valid argument. Likewise, this duvet deserves a larger zipper with a cord, which can be pulled to close or open, without risk of getting stuck or breaking. In fact, it often gets stuck with the zipper which catches the duvet.

Zipper

The problem with this product is the zipper, it is the zipper. I have had two jackets and both have given me problems with the zipper. Otherwise it is a good product. José Luis Fernández.

Perfect

It was not for me, but for my son, who is a soldier. He's gone on maneuvers with this bag and it's done pretty well, so it must be pretty good.

Well designed, comfortable and…

Well designed, comfortable and warm at 0 degrees

My son is delighted...

My son is delighted with this sleeping bag which keeps him warm in the tent even when it freezes a little at night (around -2 or -3°). The sleeping bag is a bit big and takes up space in the backpack.

Additional Product Information

Composition

Padding: 100.0% Polyester ; Main fabric: 100.0% Polyester ; Carry bag: 100.0% Polyester ; Lining: 100.0% Polyester

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.

Style

Want to know more about the wadding?

We use 2 layers of overlapping wadding: - One of 115 g/sqm, 100% polyester,- and one of 150 g/sqm, 100% polyester.The wadding is made from silicone-coated spiral fibres that make it highly compressible and highly durable.Despite its low thickness, it has high insulation properties thanks to the air trapped inside, and remains lightweight.It retains its warmth even when wet.

Compatibility

Can be twinned with all the Forclaz MT500 sleeping bag models.Can be twinned with the older models in the 2017 ”Ultralight” and 2018 ”Light” ranges.

Product testing

All our sleeping bags undergo mechanical tests that test the performance and resistance of the sleeping bag to guarantee better sleep and recuperation (thermal resistance, resistance to abrasion, comfort, etc). We also carry out many tests in the field, in real conditions.

Storage instructions

You can easily store your bag by stuffing it loosely into its cover, feet section first. To keep it fluffed up & ensure good thermal performance, remove from its cover, extend, store it in a dry place.
