The Survival One sleeping bag was designed by the brand Carinthia to protect you in extreme conditions. The zipper is doubled with a flap to repel wind and moisture. This sleeping bag features a differentiated lining: this means that heat is better retained and your movements during sleep only compress or move the inside of the bag, not its entirety. To top it all off, you can slip your arms into the lining designed for this purpose to wear it like a coat. A blend of protection and ergonomics to offer you the best sleep in extreme conditions.
