I bought a pair recently, about four months ago. Comfortable, really liked them. About a month ago i noticed wearing in the material, about an inch to the right of the zipper. Tonight they've full worn through, almost like there was a weak spot in the material. It wasn't a crease, wasn't stretching, etc. Anyone had quality problems with their Sartso's? Shits me, because I don't have the receipt so i can't even prove when i got them if i tried to get them replaced. Certainly won't be buying them again.
