Gradient Hat
I LOVE this hat!!! The Gradient Hat is made of wool and as a result it is SOOO warm. Unlike fleece hats, this hat does not allow wind to penetrate due to its tight wool weave. It looks great, too!!

Another fantastic product from OR. This hat has pretty cool styling and it of course keeps your noggin toasty warm. Buy it, you won't be disappointed!

Comfy for Moderate to Cold Weather
The boiled wool has a nice feel to it and the material is relatively thin (thicker around the ears where there is an inner fleece liner), but warm. I bought two OR "one size fits all" winter hats recently and they fit very well (I usually wear an OR medium), covering the ears nicely with a little bit of room up top to spare. The fabric is not super dense and I would rate wind resistance as moderate. If outside in bitter cold (single digits and lower), this hat would be best used with a jacket with a hood to help trap heat. Overall a good all-around hat that will meet most of your winter needs and it looks good too.

Great beanie
The hat is comfortable and attractive. It fits snug around the sides of my head without being overly tight. It's made of dense, quality wool that appears durable and keeps my head warm no matter how hard the wind blows or how cold the weather is. I would prefer if there was less room in the upper part of the hat, I have a small head so it doesn't fit flush against the top of my skull, but this is forgivable since other people may need more room upstairs. I like the style of the hat and will buy more in other colors. The soft inner headband feels comfortable against my ears and forehead and provides a bit more insulation to seal out the cold right where it's needed. It took me a while to find a hat that looks good and performs as I'd hoped. Would recommend it to anyone.

This is a great hat. Handsome design (I bought it for my husband) and very warm. The fleece lining makes it very comfortable and the rest of the construction provides excellent warmth. Highly recommend!
