The Climate Series Adaptative Liner is designed to regulate body temperature during high-output winter activity. Made with a 170 g/m² Polartec® Power Grid® fabric, its grid construction enhances breathability, reduces bulk, and helps manage moisture as effort increases. Lightweight and technical, it can be worn on its own for active movement or layered under other pieces when conditions demand more protection. Ideal for ski touring and other dynamic winter pursuits, this liner prioritizes comfort and thermoregulation to keep you moving efficiently throughout the day.
