Not very itchy, easy to put in your pocket and warm
Color: Black
I wore turtle fur for a long time and liked it except that it's too big to fit in my pocket. This wool product has really impressed me so far. It doesn't have a zero itch rating but it is very soft. It's surprisingly warm for its weight. Fits easily in my coat pockets. It's comfortable, fits well on both my neck and face as it has some stretch to it. It had a smell when I first opened the package but that went away after a couple of days. I wore it around my neck in 20F and was warm. I would say that using it as a face mask at that temperature would be pushing its limits. I find it to be a good balance between size and warmth for the Kentucky tri-state area in a mild winter. Because of it's size you can easily put a layer over it during extreme cold and it would be well worth the space it takes in your pocket

Too Short
Color: Burgundy
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.
