The Turtle Fur 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 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 Turtle Fur's 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.
