Penguins can't fly, but they sure can look it. This fan-favorite, animal design sock offers day-long comfort and warmth thanks to soft Merino Wool. A solid choice for any day on the mountain, the Penguin Peak will keep you at the top of your game by avoiding foot pain with a supportive arch and unbelievable fit. The midweight cushion warmth will keep you climbing hills to slide all day, and night. Penguins don't ski either, but they sure can fly... on snow.
