I just wanted to share my thoughts on a product that I really like for cold weather...Mad Bomber Hats
These are warm, versatile, adjustable, have a soft brim to get out of the way of scopes/binos/bowstrings, can have the brim snapped up out of the way completely when desired, can cover the ears and neck or just the head, have earbud holes for headphones if desired, have real rabbit fur, come in a variety of colors/materials all of which just about can be had for $25 on sell if your patient, and just plain rock for winter hunting. Your measures may vary but I just snagged two more locally for $43 out the door at Cabelas. In my limited experience, they are much better than a wool hat, ball cap, Kommer hat, beanie, etc for winter hunts.
I keep hoping to find a brown leather one on sell to go with my leather coat for work.
