Our designers, who are all trekking enthusiasts, designed this sleeping bag to sleep comfortably in a bivouac at temperatures above or equal to 15°C.
It is ultra compact and lightweight – perfect for summer use. The 2 side zips with double sliders provide optimal ventilation. This sleeping bag can be twinned.

- 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.
- 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. Shoulder width 70 cm, height at feet 32 cm in size L, 62/28 in S, 66/30 in M, 74/34 in XL

- Ergonomic hood with drawcord. 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 one layer of 100% polyester wadding at 60 g/sqm. 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.
- When trekking, you may well get a tear in your sleeping bag! The good news is that it can be repaired to prevent the tear from getting bigger or the synthetic fibres from escaping. We recommend using self-adhesive repair patches (ref: 8584596). If you don't feel comfortable doing this yourself, we offer a repair service in our Decathlon stores and one of our specialists can apply a heat-bonded patch for you.
- This sleeping bag is guaranteed for a period of 5 years from the date of sale indicated on the receipt. A product covered by warranty will be repaired or exchanged free of charge. The warranty covers product defects excluding any resulting from normal wear and tear and those resulting from abnormal use.
