Therm-a-Rest New Thermarest Universal Repair Kits Orange One Size

It stays very secure and watertight, and was easy to apply.

Fast delivery, good quality, my mat was older, so only the patch for older mats stuck. It is all sealed again.

Effective, used on a self‑inflating mattress from Go Sport

It worked well with my Thermarest mattress; since using the kit the mattress is sealed again. What surprised me a bit was that in the end I didn’t need any patch for small holes at all, but instead ended up gluing the holes. But it’s fine – if it works, that’s good :)
