The Darn Tough Men’s Pennant RFL Over-The-Calf Ultra-Lightweight Ski/Snow Sock (Style 8002) in Seafoam is a men’s ski and snowboard sock built with the RFL (Race Fit Lightweight) no-cushion construction — the thinnest, most race-oriented sock Darn Tough knits for ski and snow. The over-the-calf shaft rises above the top of ski-boot and snowboard-boot cuffs so there’s no edge bite against bare skin during long mountain days. True Seamless toe construction closes the front of the sock smoothly, so there’s no seam rub inside tight-fitting ski boots.
The knit — 60% Nylon, 35% Merino Wool, 5% Lycra Spandex — runs nylon-forward for a thin-profile fit that maximizes boot feel and power transfer, while the merino percentage handles moisture wicking across cold chairlift rides and hot spring laps. The 5% spandex keeps the shaft locked up the calf through aggressive turns. Seafoam is a bright cool-toned colorway that pops against dark ski kits.
