Training coverage, all-season versatility. The Performance Long Sleeve T-Shirt is made from an 87% polyester, 13% spandex blend at 200 g/m² — lightweight, stretchy, and moisture-wicking for running, gym, or outdoor sport. The raglan sleeve construction allows full shoulder mobility, while the skinny regular fit keeps it streamlined under a vest or worn solo. A spring, summer, and autumn performance staple.
