I've got a men's large RAB Infinity Hoody (bright red) and it's bigger than I'd like. Had it ~18months and in that time I've actually worn it maybe 5 times and had it in a pack 8-10 times. Looks brand new, no damage. It's been hanging in a cool, dark place. I've gone in a fluffed it a few times so not sitting in the same spot on the hanger.
If you've got a Med in the same thing or something similar (down or 100wt synthetic), I'd be happy to trade. I'd also sell it. Shoot me a message and I'll get you a photo.
