Get out your green. 3/17 is an important day for many, so we put this design on a green heather crewneck tee for both the Unisex and Ladies' styles. The shirt is a very soft and comfortable 65% polyester and 35% cotton. Add a festive layer to your green. If you're worried about how these sizes fit your bod, check the sizing chart up there in the pull-down menu. Three-seventeen!
