The 40 Grit Short Sleeve Performance Tee is built to keep you comfortable. Go ahead, get to work – whether it’s your day job or your latest enterprise or adventure. 100% polyester textured knit wicks moisture, feels good and is just the right weight for activity. Built better with a smooth taped neck (no scraggly, scratchy neck seams) and rib-knit neck trim to look good over many washings, not come out of the dryer looking like something the cat dragged in.
