Description

The Russell Athletic R21CPM CoolCore Half Sleeve Compression Tee is a performance compression shirt designed for teams and athletes. It features 84% polyester/16% elastane Xtreme compression cloth with 92% polyester/8% elastane stretch mesh inserts on the center back and underarm for targeted ventilation. CoolCore technology helps distribute moisture and dry the fabric quickly, while UPF 50+ provides protection from harmful UV rays. The four-way stretch construction allows increased mobility, and the half-sleeve compression design provides support to the upper-arm muscles. The crewneck collar and raglan sleeves provide a classic athletic design with added range of motion.

The R21CPM features a moisture-managing construction suited to active training and competition, with a dropped tail for additional rear coverage. The tag-free label helps provide a comfortable fit, while the "R" logo on the center chest provides Russell Athletic branding. Designed for use as a compression layer or athletic base layer, the shirt combines stretch fabric, targeted mesh ventilation, moisture management, and UPF 50+ protection in a streamlined half-sleeve design.
