- Chad M.Verified BuyerRated 5 out of 5 starsWorkout Shirt
Lite material and perfect for workout gear. I would recommend going down two sizes. The size chart is different than their other products, so just pay attention, as this runs big-big. Example, for their regular fitted shirts I am a 49cm Chest, XL; however, here the M is a 59 and small 57. They do run that big, I went down to a L and it swallows me. However, it's for working out and I am fine with it...... just a heads up. Otherwise, awesome material, and size chart is true, this was on me!!!

Never been in a more comfortable workout shirt. Or for the hot days on the field when coaching or playing, just a great combo of fit and material
