Perfect low-cut sock!

I've used it several times

This sock rocks! I love the comfort and thickness, plus the merino wool doesn't smell at the end of a long day! I love the tab on the back that makes it almost impossible for the sock to ride down.

Cool and Light

I've put it through the wringer

I really like these socks. They are thin, keep my feet cool and dry, the material is comfortable, and they have cool patterns.

Wearing these right now

I've used it once or twice and have initial impressions

So far so good. They don't feel different than other sport socks I've worn, but that's not a bad thing. They fit and feel great. If these survive the test of time and the washer, they will be my go to sock.
