Unfortunately these shirts don’t work for me. The sweat stays on the shirt specifically on the back becoming a wet sponge. This makes it very comfortable to run in. Not only that, it’s not stretchable so when you take it off, the trap sweat on the back makes it so much harder to take the shirt off. I kid you not, I had to ask my wife to help me. I expected more from such a pricey shirt especially with the perforated holes. I realized it doesn’t matter because the material sucks.

Great wieght slim cut. Very cool...............AK rocks

Performance fabric. Excellent for wicking away moisture and keeping heat retention to a minimum.
