Abstract: An athletic shirt has a sleeve made of Spandex Lycra which extends in a generally cylindrical shape from a relatively small cylindrical cuff to a mid portion and then in a curvilinearly expoanding upper arm portion to a relativley large shoulder portion joined with diagonal seams to a high bulk shirt body with a front opening placket. The sleeve is tightly knitted with fine threads, is lightweight, is fast drying, is stretchable in more than one direction and is highly resilient, for lightly uniformly gripping an arm and shoulder and allowing free expansions and directional orientations of the arm without separating from the arm, while maintaining a uniform temperature and rapidly releasing perspiration in a fast drying manner. The body of the shirt is made of a high density high bulk relatively tightly knitted cotton material having stitches larger than the arm portion.
