Not all cotton is created equal. Unless they're in a 2-pack. Our Combed Cotton Tee is a sharpened essential, refined at the fiber level, finished with a balanced fit throughout the body and a reinforced neckline that holds its shape.

The fibers are combed before spinning, which means the shorter strands that cause roughness and inconsistency are removed. What’s knit is a smoother, stronger fabric with a uniform finish.
