Who is Pure Athlete? At Pure Athlete, we are the manufactures of the bestselling snowboard and ski socks for men and women on Amazon. We have spent countless years perfecting our technology to provide an advanced ski sock that fits comfortably while offering superior performance. The Camo Ski Socks feature premium merino wool to keep feet warm. They are moisture wicking and anti-odor – this prevents the buildup of sweat and stink. The merino wool is non-itch to ensure comfort. Special light hexagon padding in the shin area is designed to reduce shin bang. The warm winter socks are able to be used for both skiing and snowboarding and are design to last season after season. A no-slip cuff located at the top of the socks keeps the socks from sliding down. 100% Satisfaction Guarantee: We know these are the best snowboard socks you will ever wear. We guarantee it! If not fully satisfied for any reason, we will refund your purchase in full – no questions asked.
