I used these for the summer as a delivery driver. I was always out in the heat and I needed something thin to wear under my shirt that could wick away the sweat and keep me cool in 100 degree weather for 12-14 hours a day. I would recommend to anyone who works out at well. My main critique was that the size I got was a little long, maybe if I was 6” tall it wouldn’t be so much like a skirt haha but it was mainly for an undershirt for my uses anyway.
