very long hat
December 02, 2010

This hat is about 3 inches longer than most beanies. Good if you have a big head (it will cover your ears), not good if your head is small. If you have a small head, the hat poofs on the top (looks weird) as you cannot pull it all the way down without completely covering your eyes. I don't know about quality, have not worn it yet. It is made in China, unlike a lot of other wool hats. It is more of a mid-weight hat with full fleece lining - nice for cold days.

Nice choice for cold day
March 04, 2012

I bought this hat for my brother and he really likes it. This hat covers ears that is quite important when it's cold outside. I bought it for full price, so now I'm thinking to buy one more with discount.

Pros: Great design, Build quality, Ease of use

Warm and Covers Ears!
February 01, 2011

Really love this hat. Fully lined with a nice fleece interior, stretchy, easily fits over ears completely and I've tested it down to 0 degrees F and it was perfectly warm. It's become one of my favorites and it's an easy one to recommend.

Pros: Great design, Build quality, Performance, Ease of use, Great value
