Cheaper and better than other brands.

Really like these. They're a heavier, "lightweight" than I expected, but that's not bad. Have been buying Wigwams for a long time, but they don't have great longevity. The REI brand is cheaper and seems just as well made. I like the muted earth tones instead of the "HEY EVERYONE LOOK AT MY SOCKS" that other brands make. No complaints. I wear a men's size 15 and the largest size of the REIs fit well.

Soft

Soft and cozy. Don’t a lot of stretch in the top so they fall down easily.

Excellent Socks!

I really loved both pairs of these socks I got. We were camping without access to showers for several days and I never felt like I had to change these even after wearing for a couple of days. They stayed up on my calf and were very comfortable.

Sizing is inaccurate

The xl size is only a l and very small. I have worn REI socks for years but they are not consistent with their sizing.. Had to return them.

good solid socks for winter sports

We bought these socks for my daughter to wear while cross-country skiing (Nordic) and she likes them. They wash well. I line dry.

Warm Pillows for the Feets

These are thick and cushiony and soft and warm! They seem a little big but not too big. Love them!
