Vapor Solar Performance fabric, made of 100% Microfiber, featuring up to UPF+50 solar protection, keeping the sun's rays from penetrating through to your skin. The Skin Cancer Foundation recommends this fabric as an effective UV protectant ONLY for areas covered by garment. Durable, yet comfortable and lightweight, soft to the touch, and powered by PURE-tech moisture wicking technology, Vapor apparel and accessories are perfect for wearing outdoors, keeping you cool and protected from the sun all day long. Zinc based technology fights against odor and allows you to stay fresh throughout the day. During cold months, fabric is thin enough to allow for comfort and warmth without the bulky layers - making it the perfect multi-season apparel and accessories for those working or playing outdoors.
