Sea To Summit Air Mat Repair Kits are a quick and easy solution to fixing punctures in inflatable sleeping mats when on adventures. 

The pack contains eight self adhesive fabric patches - four small round ones and four larger square ones - and are easy to apply. Just peal off the backing paper and place over the puncture. You will need to leave it inflated for at least 30 minutes so the glue can cure and set. 

There are full instructions for use included in the repair kit.
