Product Customer Reviews
Very comfortable to use
I am completely satisfied! I wanted to take a small, small Sulyu fishing bag for travel, on trips (airport package, plus day bag) I typically slept in the room, so I used it within the comfort zone. On warm days, even this leads to a warm morning - but there is nothing you can do about it. It is easy to handle, and can be easily folded into the holder's bag
Takes up very little space when folded, effective at temperatures around 15 degrees.
Great sleeping bag, warm (holds up to 10 degrees) and comfortable, only if everything closed it is a bit tight. Very easy to open and close in the bag.
The sleeping bag is very storable when folded and in a compression package, which was one of the main reasons for the purchase. It was used in the mountains in the summer months in a tent at night temperatures around 13 degrees, but so far only for a few nights. I felt very comfortable with the foam mattress with minimal insulation. I was neither cold nor hot. However, the girlfriend was cold from below, so it would need a mat with a higher thermal resistance and it would be fine. The zip fastening is on both sides and the upper part in the face area can be easily pulled down with a single drawstring. For me, the ideal sleeping bag for travel when I need it to take up as little space as possible.
Lightweight and practical
Alright
Good
Ideal for summer when the minimum temperature does not drop drastically yet. it is small and easy to pack, so I can only recommend it to everyone.
Used in the mountains in summer, it does its job. Light to carry and compact
Expensive considering the quality of the materials
Its small size makes it convenient to carry
OK but expensive
Recommended. Acceptable weight, good packing size (wish: 5-10cm wider would be great)
The sleeping bag is tiny but warm. Perfect for summer. In the mountains, when the temperature dropped to about 10-12 degrees, it was enough to put on a sweatshirt and it was fine.

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.
