UPDATED FOR 2020!

A long standing favourite with car and family campers that want supreme comfort, this Therm-a-Rest BaseCamp Mat, with its 5cm of premium self inflating foam, now features Therm-a-Rest's new WingLock valves for quicker inflation and deflation - making it even more perfect for taking some extra comfort on your next trip!

Made from a durable yet soft to touch polyester fabric, this self inflating Thermarest mat, has a compressible foam core, which expands when unpacked for easy self-inflation and for an excellent level of cushioned comfort.

And now, the new WingLock Valve which has been added, which has 3 times the airflow rate of the classic valve to make this luxurious self inflating mat it even easier and quicker to inflate and deflate.

This Therm-a-Rest Basecamp Mattress is the large version which measures at 196cm long with a standard 64cm width with a 5cm thickness for extra warmth and support.

Here at OutdoorGear, we think this is an outstanding and generous sized 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 car and family camping.
