Our liners are thoughtfully designed as the base layer of warmth in our Heat Layer System, creating a smooth, second-skin fit that feels comfortable and responsive. Crafted from premium materials like Merino wool and Polartec® fleece, they excel at wicking away moisture to keep your hands dry and comfortable.

For colder conditions, the full Heat Layer System lets you dial in your ideal level of warmth. The Shell mittens provide essential insulation and serve as your primary barrier against wind and snow, while the Polar Hood adds extra protection to shield your hands from moisture and biting winds in the most demanding environments. By combining the liner with the Shell—and adding the Polar Hood when needed—you get a fully customizable glove system that adapts effortlessly from a mild chill to extreme cold, keeping your hands comfortable every step of the way.
