After wearing these shirts for over a year, I have to say they fill every need. Sleepwear/Home use to active lifestyle. As a firearms instructor I have made these shirts apart of my attire. They hold up pretty good to the elements. Evaporation is not an issue. You really do stay cool and dry. Odor control. Light weight. It's nothing to grab an extra shirt an throw it in you bag. My only requst guys save some for me! Dont buy them all up!
