I honestly thought the fleece would be thicker, but after using it, I'm glad it isn't. It kept me plenty warm in a tree stand at 40* with a breeze on a recent outing. If you are a fan of buffs, the polar buff is phenomenal for cold weather! When making it into a beanie, because of the added material, it ends up being a really deep beanie that you can roll up the sides to add even more warmth over the ears. I doubt I'll ever need a balaclava or neck gaiter again.
