Good all around sock
Size: Large, Color: (498) Coyote / Coyote / White
Great fitting and lasting boot sock. Comfortable, lasting sock good for boots or daily wear. Warm when it needs to be warm and cool when it needs to be cool.

Great socks
Size: Large, Color: (002) Black / Black / Castlerock
These are the only socks I’ll wear when working. They are so soft and comfortable. They are thick and heavy duty, and don’t wear fast. The fit snug and perfect. Good warm with a little compression for being on your feet all day.

Good boot sock
Size: Large, Color: (001) Black / Black / White
Used these for over a year now. They cover your calf and really don’t move from that spot. Very comfortable.
