The Tri-Titan's reversible sublimated singlet comes with a perfect blend of Polyester and Spandex for optimal comfort and durability. The 4-way stretch material moves with the body to support the most agile athletes, while being held together with our double-stitched, and flat locked stretch threads. Our ink is dyed deep into the fabric to ensure a strong, saturated color, even when stretched out. Unlike other reversible graphic singlets, Tri-Titan's has a signature SINGLE LAYER of material, keeping the singlet lightweight and comfortable.
