Good product

A good sleeping bag at an affordable price. It is warm, light, and I don't feel like it loses any comfort after prolonged use. A good choice in the warmer months for those who are cold.

I bought one…

I bought a third because the previous one, the closure to close the bag is defective.

Solid sleeping bag

the sleeping bag looks good, the temperature extreme has never been tried, suitable for the period May - September.

sleeping bag for big sleep

Good value for money, not for -20° in the tundra but warm enough for a night in a tent in the mountains in summer!

Good value for money

Bivouac sleeping bag that meets its description. Unbeatable value for money. Tested under 10 degrees, at 1500m. Don't expect a breathable product.

A cost-effective and practical sleeping bag.

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?

We display the comfort temperatures on all our sleeping bags, tested by an independent laboratory (AITEX) in compliance with European standard 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

A generous mummy shape that is wide at the shoulders and narrow at the feet to optimise thermal insulation (no heat loss) and make the product more compact, while maintaining some freedom of movement.Width at the shoulders 70 cm, height at the feet 32 cm in size L. 62/28 in S, 66/30 in M, 74/34 in XL.

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.
