Hi there! Am mid way through a tour and the top layer of my thermarest (it isn't the brand Thermarest but is the same design) has started coming unglued, meaning that it balloons on one side and the rest of the mat loses air to the bubble... am really hoping not to have to buy another as they are pricey and this one has no other problems, no punctures etc. I wondered about some kind of glue that would sink through the top layer and re-bind the lattice thing to the cover. Anyone successfully done this or know what to buy?
If you know how to fix this please let me know!
