I'd call the manufacturer or have a dealer do so. Bare replaced my breathables, no questions asked, no charge other than my cost of shipping to them...they were 2.5 years old. I couldn't find holes by filling them with water, they just plain leaked all over it seemed.
I've had various things replaced no charge, long out of warranty, by simply sending the broken, damaged, worn out, whatever, to the manufacturer or it's Canadian distributor along with a nice letter saying more or less....love your products, used them for years, still will, obviously I need to replace this particular piece, but am hestitant to do so if this is going to happen again.
Columbia flats shirt, ICOM VHF battery, tent poles, Cortland fly line, sprinkler timers..just a few examples. Good companies like to keep loyal customers.
