Buff Polar Reversible Multifunctional Headwear has been re-engineered and is now designed with a 4-Way, ULTRA STRETCH fabric construction, that features UPF 50 protection, and 100% recycled REPREVE Performance Microfiber. Polar Reversible multifunctional headwear has 8 different wearable variations. Microfiber on one side breathes, and wicks moisture. Polar fleece lining on the other side elevates warmth and is soft and comfortable next to the skin. Wear fleece side out or fleece side in, or maybe a little of both depending on conditions and your mood.
