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.

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.

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.

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.

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 72 cm, height at the feet 34 cm in size L. 64/30 in S, 68/32 in M, 76/36 in XL.

Size S: 1450 g, user up to 1.59m tall. Bag dimensions: L 42 cm Ø 19.5 cm. Volume 12.5 L.Size M: 1550 g, user from 1.60m to 1.69m tall. Bag dim.: L 42 cm Ø 20.5 cm. Volume 13.9 L.Size L: 1670 g, user from 1.70m to 1.84m tall. Bag dim.: L 42 cm Ø 21.5 cm. Volume 15.2 litres. Size XL: 1790 g, user from 1.85m to 2m tall. Bag dim.: L 42 cm Ø 22.5 cm. Volume 16,7 L. Volume & dimensions may vary according to the compression applied to the product.

Ergonomic hood with drawcord.Double collar for protection from the cold.A baffle along the zips prevents heat loss.Double-slider zips for optimal ventilation.The top of the sleeping bag can be opened with the two side zips.

We use 2 layers of overlapping wadding: - one 115 gr/m2, 100% polyester (70% recycled),- and one 150 gr/m2, 100% polyester (70% recycled).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.

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.

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.

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.
