When we successfully get our kids to strap into skis instead of belly-sliding down the sledding hill, we finish their on-mountain kit with the Darn Tough Penguin Peak OTC Midweight Cushion Sock. Soft, toasty, and moisture-wicking merino wool keeps kids' feet at the best temperature during active lessons and frigid ski days. Darn Tough's thoughtful construction keeps the sock in place to prevent bunching, sliding, and discomfort. And cushioning under their feet keeps them comfortable enough to ride lap after lap.
