The Rundown

Start warm. Stay warm.

Developed for winter athletes who like to bring the heat, the reimagined I-Thermic X-Warm base layer top 2.0 builds on its predecessor with an integrated heating system that can be controlled via your smartphone to deliver warmth where you need it most. Now with a more streamlined fit, longer battery life and enhanced app integration, this base layer is ideal for a wide spectrum of start-and-stop winter activities - from the ski lift to lunch on the patio to après-ski - using 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 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.

ULTIMATE COMFORT. UNRIVALLED FUNCTION.

Base layers without equal for wherever you lead the day.
