Comments: When I first opened the package my initial thought was that it would be too thin. My first time running with it was about 35 degrees and blowing 15-25 mph out of the north and yet I was still warm. I've been very pleased with this beanie I only wish it was a little longer for a bit more coverage. Still a great and warm beanie.

Comments: I love Smartwool. Comfortable, durable, quality products that wear well over time. Don't get me started about their amazon socks. The brand & appearance are why I bought this hat. It's super thin & super light. My one concern is that it is sized a little large. I wear a 7 hat & this wasn't too snug. Haven't decided if this will be for running or casual wear. it does look nice.
