Hmm. Not sure of the fabric, will look it up, but it's a Speedo suit in their Endurance fabric. I really hate to dump it because I love the design (dark blue seguing up to medium blue in a kind of Matrix-pattern), but this rash is gonna kill me. I'd think it was the suit being too small, because I've had to struggle to get into it ever since I bought it, but I've used it without problems for over a year and it's fit beautifully once on. I have big shoulders from climbing, but surely that's common among swimmers too. So I think the size is right and it's just the material getting saggy some places and starting to shift a little.

Thanks for the feedback!
