Trekking sleeping bag - MT500 5°C - Polyester

We display on all of our sleeping bags, the comfort temperatures tested by an independent laboratory (AITEX) according to European standard ISO 23537-1:2022. The comfort temperature is the lower limit of comfort at which a person in a relaxed posture is globally in thermal equilibrium and feels neither cold nor hot (determined for a standard woman and under normal conditions of use). Choose your bag sleeping depending on it.

The comfort limit temperature is the temperature limit at which a person in a curled up position in their sleeping bag is globally in thermal equilibrium and is neither cold nor hot (determined for a man and under normal conditions of use). recommend using an insulating mattress to optimize your thermal comfort.

In the context of this standard, the protocol for measuring the thermality of a sleeping bag uses a mattress whose thermal resistance corresponds to an R-value of 4,8. This means that by using a mattress with less insulation, the thermal performance of your sleeping bag will be lower. We therefore advise you to use an insulating mattress in order to optimize your thermal comfort.

Dress simply (1 single layer of clothing is enough). Warm up your extremities: hats, gloves, socks, hand warmers, frictions... A flask of hot water can be used as a hot water bottle (if there is no risk of it opening unexpected!).Contract your muscles (70% of the energy consumed is transformed into heat), but without making any movement that generates a cold draft.Use a bag sheet to optimize the heat and avoid over-washing your sleeping bag.

Generous sarcophagus shape, wide at the shoulders, tightened at the feet to optimize thermal insulation (no heat loss) and compactness, while maintaining relative freedom of movement. Shoulder width 70 cm, height at the feet 32 ​​cm in size L. 62/28 in S, 66/30 in M, 74/34 in XL.

Size S: 980 g, user up to 1m59. Cover dimensions: L 40 cm Ø 17 cm. Volume 9,1 liters. Size M: 1100 g, user between 1m60 and 1m69. Cover size: L 40 cm Ø 18 cm. Volume 10,2 liters.

Volume and dimensions may vary depending on the compression applied to the product.

Ergonomic hood with drawstring.Anti-cold flap along the zips to prevent heat loss.Double slider zips for optimal ventilation.Possibility to open the top of the sleeping bag thanks to the 2 side zips.

We use 2 layers of wadding: - one of 60 gr/m2, 100% polyester - and one of 115 gr/m2, 100% polyester. It has the advantage of retaining heat even when wet.

Can be combined with all models of MT500 Forclaz sleeping bags. Can be combined with the old models of the "Ultralight" 2017 and "Light" 2018 range.

On a trek, a hitch on a sleeping bag, it can happen! The good news is that it can be repaired in order to prevent the tear from getting bigger or the synthetic fibers from escaping. We advise you to use self-adhesive repair patches for this (ref: 8584596) .And if you don't feel comfortable carrying out this operation, an iron-on patch application service is available in the workshop in your Decathlon store.
