When the weather heats up and you need breathable protection for your arms, reach for the adidas Run Arm Sleeve. These arm sleeves feature an engineered mesh fabric that allows air to flow and helps dry sweat as it builds on your arms, so you can stay focused on the run, not on how wet your sleeves feel. Finished with jacquard 3-Stripes and a reflective 3-Bar logo, they add extra flair and visibility when the sun goes down.
