"2XU® Compression Arm Guard (Single): The 2XU Compression Arm Guard (Single) is a compression accessory built for athletes who need targeted arm support during dynamic, repetitive movements like basketball, tennis, rowing, baseball, and gymnastics. Graduated compression technology wraps your forearm, elbow, and biceps to help stabilize muscles and promote blood circulation, so your arm warms up faster and works more efficiently throughout your activity. Moisture-wicking yarns pull sweat away from skin to keep you dry during intense efforts, while UPF 50+ sun protection shields your arm from harmful UV rays during outdoor competition and training.Made from a 72% Nylon and 28% Lycra® blend, the guard delivers the compression support you need without sacrificing breathability. An antibacterial treatment reduces odor-causing bacteria, so the guard stays fresher through repeated training sessions without constant washing. Whether you're serving hard on the court, powering through rowing intervals, or training in full sun, this single arm guard provides reliable compression, moisture management, and UV defense in one versatile piece.Why Our Fit Experts Love It""I wore this during a tennis match and appreciated how the graduated compression kept my arm stable through serves and volleys.
