i got the comperssion crew shirt and the v neck from underworks. size small (its what i wear in mens shirts) and the black one (cotton) feels great! but im having a really hard time with the other one, its a complete pain in the a** to try to get on and off, it works really well, but it rolls up alot and isnt very comfortable, should i send it back and get a medium? or is this typical with the shirts?
