Thermarest's most durable repair option with a 4-hour cure time.
The Permanent Home Repair Kit uses a wet adhesive and fabric patches to make the strongest and most durable Therm-a-Rest® mattress repairs possible. It is also the best choice for repairing larger tears. Works on all Therm-a-Rest mattresses, including NeoAir.
You will need also a way to mark the leak (marker, pen or tape) and scissors or other cutting tool.
