Nice, warm, and not too thick to make you sweat. I find there is little extra room (I would consider myself having a medium sized head) but the extra space does not cause the hat to feel uncomfortable or look ridiculous. It will definitely keep me warmer than some of the other thinner style hats out there.
I bought this for my boyfriend as a gift. It fits him well and snug and goes over the ears, so he loves it! He works on the flight line, so hes constantly outside during harsh cold weather. It keeps him warm.
Decent beanie. It's light and fairly warm. Not warm enough for extreme lows or wind. In those instances I use my wetzel hat. I do wish it was a little smaller with some stretch. I have a smaller head and if it was smaller but had some stretch, it could fit me or stretch to a larger head.
