The Split Short-Sleeve Crew Shirt features revolutionary FlashDry technology, which incorporates volcanic rock into the fibers to provide exceptional breathability, quick drying, and moisture wicking. Rugged 50-denier, 100% polyester waffle-knit fabric has a honeycomb texture which further enhances moisture movement and adds just the right amount of stretch. Built-in UPF 15 sun protection helps shield your skin against harmful UV rays. Strategically placed laser-cut venting panels ensure maximum ventilation for long-wearing comfort. Flatlock-stitched seams offer added strength and reduced abrasion, while the gusseted underarms allow greater freedom of movement. Imported.
