Part of the Summit range, this self-inflating camping mat provides extra comfort and insulation to help you get a great night's sleep.
The mat is extremely lightweight and features an integrated pillow that's easy to inflate. The mat rolls up tight into two elasticated straps, making it easy to store, transport or attach to your backpack.
Ideal for festivals and hiking, unpack, shake it out and inflate the pillow for a nice, soft layer between you and the ground.
