I like the material and construction; it's soft and thick. It is warm and is effective at temperatures in the teens and winds around 30 mph. The thickness of the material helps prevent my breath from instantly condensing and moistening the fabric. I never got the "wet dog" smell wet wool is known for. Its fit is a little tight but not prohibitively so. The color matches that of the beanie. It's too sort to be considered versatile. In wind I had to choose between shielding my neck or my face. I HIGHLY recommend you not machine wash and dry. Hand wash it and let it dry naturally.

Nice for the money

Color: Army Green

Nice but not the most comfortable and came with an interesting smell. I with it was a bit thicker but the build quality is nice and it does look nice. For the price, I'd buy again. I use it primarily for skiing.
