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 sun protection, and REPREVE Performance Microfiber. The Microfiber on one side breathes, and wicks moisture, while the fleece lining on the other side elevates warmth and is soft and comfortable next to the skin. There are 8+ different ways to wear.
