In my opinion the shirts run small. I returned 2 shirts & tried to exchange for a 3rd, but wasn't permitted. Had to get a refund. Was really hoping to help my husband with his shoulder. I suppose if you have a perfect physique these will work fine. Not sure I will order again.
Wearing this shirt makes me remember to keep my posture correct- and not slouch! And it feels good too! Just wish they were a bit more affordable otherwise I love them.
