What Our Gearhead(R) Experts Are Saying:"I wore these on a cold morning start that turned into a warm afternoon and my feet never overheated or got clammy. The wool did its job regulating temperature the whole day without adding any bulk in my boots."Mountain weather rarely stays put for a full day, and the Poncho UL Wool Snow Sock is built to keep pace with it. Stance blended thermoregulating fibers with responsibly sourced merino wool, so feet stay warm on a cold first chair and cool once the sun climbs higher over the afternoon. Graduated sport compression supports circulation through long lift lines and lodge breaks between runs, while Infiknit reinforcement at the heel and toe stands up to the friction of a stiff boot shell all season. An ultralight cushion keeps the fit thin enough to disappear inside a boot, and performance mesh adds breathability exactly where feet need to vent on a hard climbing skin track.
