Used it with a 3 season sleeping bag in -8 Celsius.
It worked very well. I had a 3 season sleeping bag and this liner. Temps dropped to -8 Celsius in the mountains but I slept very well indeed.

Way too overpriced!!!!
Much greater alternative to other sleeping bag liners which actually working and make a difference on temperature ratings...also pretty comfortable and nice feeling. Although is a good product after trying many other cheaper products I founded that is way to overpriced comparing with many other which performed as well
