The warmest foundational layer for winters coldest, most extreme conditions, refined with an ultra-high collar, additional odorControl, and a highly elastic wool blend for body-mapping insulation.
Merino wool and a highly elastic, highly insulating synthetic blend provide the most insulation of any of our skin layers, with an updated neck-warmer collar construction that extends the protection. The ultrasoft textile doesnt irritate like wool, and its high elasticity means it also doesnt lose its shape when it stretches. Instead, it moves with your body, maintaining a low-volume, next-to-skin fit to trap warmth and expel moisture both of which are critical for comfort in deep winter.
Our warmest skin layer textile, an ultrabreathable, ultrasoft blend that incorporates carbon fiber to provide permanent odorControl properties. Synthetic materials grant high stretch-and-return, while wool adds antimicrobial properties and natural thermoregulation.
