Product Customer Reviews
It's a go-to bag if I'm sleeping inside, or if it's warmer in winter. Two zips down the front really help with getting in and out, so much more than I thought they would initially! Small bag as well, so great to pack easily
Trekking Sleeping Bag MT500 15°C - Polyester FORCLAZ
I bought this sleeping bag specifically for the compact packdown size for bikepacking. Its surprising comfortable and warm. A great option in a premium market.
Cold nights in Forres we struggled with these light bags, not quiet wide enough for me either. Maybe 10° best for UK ESPECIALLY Scotland
I had high hopes for this product as the size is excellent- super light weight ta backpacking trip but the zip broke the first time it was used.
I really want to love this sleeping bag, as it packs very small and it's really really soft, but the temperature is just not right. At 15 degrees I am still cold and end up not sleeping because of it. The material is very slippery and against the sleeping mattress you end up wiggling the whole night. I wish I could have swapped it for maybe the warmer one at 10 degrees, but I am stuck with it now. Definitely not for UK summer.
Very bad to sleeping on
Suitable for warm nights and lightweight for hiking. Zips on either side meaning cold air flows across your body all night. Zips are cheap poor quality, is a struggle to gets zips up and virtually impossible when you’re inside the bag. Very slippy material and toggles on inside of hood meaning they irritate your face. Overall good for a night in summer.
Quality
It weighs and takes up very little space
Even though it's hot, it's confusing because you can't move your legs inside.
taken for a walk, used in a hostel, warm and takes up little space when folded
Small and warm
A spring/autumn sleeping bag with a thicker mattress will be perfect for colder days.
Used in Sweden it was very cold at night so you still had to wrap up well but it is very good you can really be covered from head to toe

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.
Tips before getting 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.
