Both pros and bros know you can't sacrifice snow feel for the sake of warmth but you also can't risk blowing holes in your socks on a three week trip to Valdez. The Darn Tough RFL Ultralight Socks are your saviors. Even lighter than their ultra light socks, the RFL stands for 'Frickin' Light' but backs up the durability department with tough nylon reinforcement in the toe and heel. True SeamlessTM construction is super smooth at all critical seams so blisters are a thing of the past. Run with the big dogs in the Darn Tough RFL Ultralight, and howl at the moon all you like.
