i have an eno with what looks like its got a thread that pulled into a wad, and i called ENO about it and they said 2 things: need a proof of purchase, will exchange if it tears. to be honest, i was not impressed with their service, i emailed twice and called 3 times, leaving messages each time and got someone on the third. he didnt offer a lot of help at all, and was very short with the whole thing.
