Therm-A-Rest BaseCamp is a self-inflating mattress ideal for all times you sleep in the environment, from hiking and trekking, to camping nights. The outer fabric that comes into contact with the skin is very soft polyester which helps to increase the comfort given by the foam padding. With its 5 cm it isolates you from the ground and makes you sleep peacefully thanks to an R value of 6. The one-way WingLock valve allows you to inflate and deflate it in an instant. In addition, the foam used is highly compressible and allows you to carry it with you thanks to the comfortable compression bag. Therm-A-Rest BaseCamp self-inflating mattress
