After one hand washing in cold water the fabric is piling. I thought that was because they're new but after a few more the fabric is falling apart, the stitches are coming undone and I have to constantly pull out wedgies but if I go a size larger they slip off my waist. I should have listened to the negative reviews, Uniqlo's Airism mesh are more comfortable, better sized (a medium in ExOfficio is sized for the borderline obese) and far more resilient. They also cost a quarter of what these do. If you don't like Uniqlo then you're only out seven bucks, buying these will cost far more money as well as a fair amount of sanity and dignity.
