COOLOMG Anti-slip Red Arm Sleeve is a great choice for cycling, running, shooting, playing basketball, football, and doing other sports. We adopt Dri-FIT® fabric that wicks moisture away and keeps you in cool conditions all the time and makes you feel comfortable. Cooling ventilation keeps you focused and agile. Flat seam construction lies smooth against the skin to prevent chafing. Compression fit allows a wide range of motion and muscle support. Available in both youth size and adult size.
