The Russell Athletic R21CPM Unisex CoolCore Half Sleeve Compression Shirt delivers the same CoolCore performance core as the long-sleeve R20CPM in a half-sleeve format suited to warm-weather training and competition. The body uses 84/16 polyester and elastane Xtreme compression cloth, with 92/8 polyester and elastane stretch mesh inserts on the center back and underarm — the highest heat accumulation zones in a short-sleeve compression shirt.
CoolCore® technology distributes moisture evenly across the full garment surface rather than pooling it at high-sweat zones, increasing the effective evaporation area and helping the wearer stay cooler through extended sessions. Four-way stretch allows unrestricted arm and shoulder movement through throwing, blocking, and overhead activity. A droptail hem provides additional rear coverage through movement without ride-up. A crewneck collar and tagless label allow comfortable extended wear. UPF 50+ rating for outdoor use.
