The Therm-a-Rest BaseCamp™ Self Inflating Mat has always been an incredibly comfortable and durable mattress, but now they have made it even warmer and more stable thanks to the updated self-inflating foam inner, ideal for getting a great night's sleep while enjoying a family or car camping trip!

This Therm-a-Rest mat is made from a durable yet soft to touch polyester outer with a compressible foam core which expands when unpacked for easy self-inflation and excellent level of cushioned comfort.

This Basecamp Mattress is the large version which measures at 196cm long with a larger 63cm width with a 5cm thickness for extra warmth and support.

Here at OutdoorGear, we think this is an outstanding self inflating mat, that weighs just over a kilo and a half and offers exceptional comfort and convenience and excellent support at an affordable price making it ideal for all season camping.
