I ordered this hat after reading all the great reviews. I wanted a windproof hat because I hate cold ears. I bought one for myself and one for my adult son. After washing it and drying it in a low heat dryer, it was so small (and it was size large to begin with) that it was too small for either of us to wear. I didn't see any care instructions indicating that it could not be machine dried. I am keeping the second hat as I want to like it, but certainly will only hand wash and drip dry it. Hope that one doesn't shrink also. Luckily, Backcountry has a great return policy which is why I shop here. It's probably a great hat, but DO NOT put it in the dryer, even on a low setting. I am taking off 2 stars for poor fabric care instructions (actually none).
