Our Comfort Shell™ Frost Liner™ is a sleek, form-fitting beanie that can be used as a standalone hat or for under helmet needs. Its thoughtful design features a silhouette with contoured ears, lined with our Micro Fur™ fleece for extra protection from the elements. The low-profile style fits comfortably on all sizes, remaining pocket-packable and helping to keep you dry, comfortable and ready to focus on the task at hand. Built for an active lifestyle, the Frost Liner™ is comprised of our proprietary technical stretch fabric, Comfort Shell™ , which wicks sweat and moves with you using 4-way stretch. The Frost Liner is ideal for all cold weather outdoor activities, including skiing, snowboarding, snowmobiling and snowshoeing.
