I've had the shirt for a little over a week or two now and I have to say, I've been wearing it almost every day since.It's given me a bit more confidence while wearing my regular clothes and, when I'm at the gym it seems to help me engage my core.It breathes well and the neck and armholes are just big enough to where they don't rub against my skin and chafe me.The only slightly negative thing I could say is that I wish it was slightly longer, as it rides up more and I try to tuck it into my pants/shorts once every hour or two.Definitely recommend it!
