This shirt fits the way I want an athletic shirt to fit. Tight, but not too tight, so it isn't bouncing around while I run my favorite route. I love the grippy shoulder design that instantly provides a cooling feeling as well as a nice design. The different materials on the front and back of the shirt provides the perfect function that I am looking for. The front covers nicely while the back mesh is very breathable. Overall, it's light, breathable, cool and good looking.
