Absolutely recommend these socks, I've had them for 2 years now and they are amazing sitting in the tree stand. I've noticed a huge difference. I bought the 400 to test out next.

I wasn't in love with the idea of spending so much on a single pair of sock. But I do not regret it at all! Best socks I've ever had, I'm going to be buying more. Makes a huge difference on those cold days.
