For permanent repairs to self-inflating mattresses, turn to the Permanent Home Repair Kit from Thermarest.
Using wet adhesive and fabric patches, this kit will give you a permanent fix to holes and tears in your self-inflating mattress. This kit does require a 4-hour cure time, so it's best left for repairs back at home, but you can be sure that when you make these repairs it will be fixed for good.
The Thermarest Permanent Home Repair Kit consists of four randomly coloured repair patches, a clear patch, some alcohol preparation pads, a wooden applicator, a tube of fabric adhesive and some instructions, so you're all set to patch up your mat.
