I've recently taken to workout/compression shirts and by-and-large I love them for even casual wear. They're great for temperature regulation and staying dry. To a certain degree, this shirt also fits the bill but in my opinion there are better options out there.This shirt is more snug/form fitting than most, which is fine. I immediately felt warmer after donning the shirt. Noticeably warmer. Almost break into a sweat warm. Not a great feeling right out of the chute. My day spent in the shirt was interesting. I almost never forgot the shirt was on, which was weird. Not necessarily off-putting, but not the most comfortable experience. It seemed to do an adequate job of sweat wicking during a normal (non-workout) day. The sleeves have a tendency to creep up into the armpits. I had no problem with the shirt creeping up the torso, which is a big bonus (and salvaged an additional star in the rating).Overall, keep shopping. There are better, more comfortable options out there.
