I recieved the shirt via UPS. Upon opening the shipping bag, I saw and felt the soft cool fabric of the NASM performance. In removing it, I tried on the shirt. The tee felt perfect on the shoulders, the underarm and waist. Was not tight, and not swimming it either. Perfect!!! I went to the gym to workout in it, and this the fabric kept cool despite a rigorous intense resistance workout starting with a 20 minute treadmill run. Never overheated or felt soaked like with wearing the altrrnative all cotton tee shirts.This performance shirt is great to wear outside the gym too. It just feels super comfortable if you got errands to run after working out. Worth the money. This tee I feel proud to wear to the gym anytime.
