Exactly what i wanted-- Football jersey material that breathes and keeps me cool; very loose and comfortable. Use for running/walking and since I have lots of trunk hair, I get hot and sweaty fast. This shirt really keeps me cool. I got white so that when running in our average 90 plus temps I don't get extra heat build up from the sun. Looks bright and fresh and I wear it every day. May get me another one soon for a spare. Downside of the matrix of holes- chest hair does pop through if you have chest hair, so not something you'd wear out in public or you'll get some strange looks. For running, I don't care if I look like I have a cat plastered on my chest.
