Nike Lightweight Running Sleeves offer protection from the weather, keeping your arms warm in the winter and shielding from the sun in warmer weather. The Dri-Fit fabric means any sweat and moisture will be drawn quickly away from the skin to help you stay feeling dry and comfortable. These sleeves are designed for adults and are unisex. They feature Nike Dri-FIT technology to keep you dry and comfortable, while the lightweight fabric provides warmth without bulk. Compatible micro-suede thumb and index finger allow for touchscreen use. The tightened wrist adds extra warmth, and a reflective graphic element enhances visibility.
