Hi @kimmy12 - Thanks for reaching out! It's great to hear that you have gotten into backpacking and already have some socks that work well while you're out on trails.

Let us know if you have any additional questions and we'd be happy to help.

If you're keen on sharing, we'd also love to hear where your winter backpacking trips have taken you. Happy hiking!

At REI, we believe time outside is fundamental to a life well lived.
