"2XU® Flex Running Compression Arm Sleeves: The 2XU Flex Running Compression Arm Sleeves deliver graduated compression support designed for runners seeking muscle stabilization and faster recovery during daily training, tempo runs, and long runs. Built with PWX Power 250D yarns, these unisex sleeves provide firm compression to your forearm, elbow, and biceps while promoting circulation before and after effort. The seamless construction reduces irritation points, making them comfortable for extended wear, and a flexible articulated elbow zone moves with your arm rather than against it, so you maintain full range of motion without sacrificing support where it matters most.The 80% Nylon and 20% Lycra® blend incorporates moisture-wicking fibers that pull sweat away from your skin, keeping your arms dry as intensity picks up. An antibacterial treatment helps keep the sleeve fresher across repeated use, while UPF sun protection shields your skin during outdoor efforts. Together, these features create a compression sleeve that supports muscle recovery without restricting your arm swing or comfort during extended wear.Why Our Fit Experts Love It""I wore these during a tempo run followed by easy recovery miles the next day.
