Developed for winter athletes who like to bring the heat, the I-Thermic X-Warm base layer bottoms use an integrated heating system that can be controlled via your smartphone to deliver warmth where you need it most. Ideal for a wide spectrum of start-and-stop winter activities - from the ski lift to lunch on the patio to après-ski - these bottoms use responsive sensors woven into the fabric in key thermal zones, controlled by the Clim8 app, which you can set to your exact preferences. Off grid? Manually adjust to your preferences using the rechargeable battery that sits neatly in its own pocket. No need to pack an extra layer. I-Thermic offers intelligent thermoregulation right at your fingertips.
