by Clam Fleece-Lined Ice Fishing Hat – Waterproof, Windproof IceTech Fabric with 150g Thinsulate (Black, One Size)

Excellent fit for my head, covers ears completely. Seems to be very durable, warm and wind proof. Will update my review after a few trips out on the ice.

This hat is comfortable and toasty warm.

I have about a dozen different hats and caps. This is the only one I have that makes my head sweat. It's that warm. It's also wind proof. If you are looking for the warmest one possible; this is the one.

Certainly warm but not quite comfortable enough to pull down around my ears. Still, very nicely crafted and I think it is still a great winter hat all-around. My problems are probably just because of my big, alien-like head, I think. I can't knock a product just because my 'little-gray-man-sized' head makes wearing any kind of a hat a hit-or-miss.

These are the best until you wash them. I think the wind/waterproof liner displaces inside, leaving you with a fleece hat which is just okay. Still for the price they're great. The liner thing is probably fixable.

Hat is very very warm.

Returned, it wasn't the same as the picture and was sized for a 6 year old.

This is a very warm hat. It is sort of a tight fleece. It is very comfortable and keeps my head and ears warm. I found it too warm for high activity work.
