"Zensah® Compression Arm Sleeves: The Zensah® Compression Arm Sleeves are a unisex compression accessory built for runners, cyclists, and team sport athletes who need arm coverage and circulatory support during training. Graduated compression works through the sleeve to improve circulation, keeping arms warm and loose across a range of activity types and temperatures. The 94% nylon/6% spandex fabric wicks moisture away from the skin, which means arms stay comfortable during sustained effort. UPF 50+ protection makes these sleeves a practical choice for outdoor training in direct sun.Pinpoint compression at the elbow delivers targeted support to that joint during repetitive motion. Silver ions are integrated into the fabric for thermal regulation, helping maintain a consistent arm temperature whether the pace is easy or hard. The sleeves function well as a layering piece in cooler conditions, so athletes can add or remove coverage without changing their full kit. Each pair is made in the USA and sold as a set, with a unisex sizing range that accommodates a bicep circumference of 9.5"" to 13.5"" in S/M and 14"" to 19"" in L/XL.Why Our Fit Experts Love This Shoe""I wore these during an early morning ride when the temperature dropped unexpectedly.
