TeamEvilGSP "Classic Logo" Printed on Next Level Tri Blend Tshirts. The term “tri-blend” tells you everything about this material — it’s a blend of cotton, polyester, and rayon. Unbelievable softness, an airy and lightweight feel, and a slight stretch. It wicks moisture away from the skin and dries quickly, unlike cotton. It’s wrinkle resistant like polyester, but more breathable, too.
