UPF 50+ is the highest sun-protection rating a fabric can carry, blocking over 98% of UV radiation—which matters more than most people realize, since a typical white cotton tee only offers around UPF 5. The CORE365 Women's Capital Performance Long Sleeve T-Shirt is built with that level of protection from the fabric itself, making it a genuinely useful layer for anyone spending real time outdoors, not just a shirt that happens to have long sleeves.
That protection comes from a 100% polyester interlock knit at 4 oz./yd²—a double-knit construction that's more stable and less prone to curling at the edges than a standard single jersey. Interlock knits also tend to hold their shape better over time, which is part of why this fabric feels structured rather than flimsy despite its light weight.
Moisture-wicking performance fabric pulls sweat away from the skin rather than letting it sit and soak in, which keeps this tee feeling dry through workouts, coaching sidelines, or long outdoor shifts. The tear-away label rounds out a design focused on comfort over decoration. This performance fabric also holds up well to screen printing and heat transfer, making it a practical choice for outdoor event staff, coaching apparel, race volunteers, or any team that needs sun protection built into the uniform itself.
