Hey athletes! These custom number compression arm sleeves are seriously cool - you can actually pick your own number to show off your favorite digits. They come in 13 different colors and 3 number color options, plus there are fun designs like digital camo, baseball stitching, and flames. The material is this polyester-nylon blend that wicks moisture like a champ, keeping you dry even during intense games. There's even a silicone lining inside that keeps them from sliding down your arm when you're moving around. Sizes range from youth medium all the way up to adult large, so pretty much everyone can find their perfect fit. The youth medium measures 14 inches long with 4-inch top and 3-inch bottom openings. Perfect for basketball, baseball, football, soccer - pretty much any sport where you want some extra arm support and style. They provide just the right amount of compression without feeling too tight, and the fabric breathes really well so you don't get all sweaty underneath. Whether you're a kid playing rec league or an adult in competitive sports, these sleeves add that professional look while actually being functional. Plus, having your own number makes you feel like part of a real team!
