On Running Solar Arm Sleeve

Stay protected and focused when conditions heat up with the On Running Solar Arm Sleeve, designed to deliver lightweight coverage and comfort for every kilometre. Built for runners and outdoor athletes, these sleeves combine UPF 40+ sun protection with breathable four-way stretch fabric, helping you stay comfortable without restricting movement. Extended hand coverage with integrated thumbholes adds extra protection where you need it most, while silicone grips on the upper inside seams keep the sleeves securely in place through every stride. Thoughtful details including watch holes on both sides, reflective silver logos and a featherlight 48g design make them a practical performance essential, whether you're tackling road runs, long training sessions or race day efforts under the sun.
