20 miles running in the shirt. I’m 5’8” 165lbs. Medium fits well. No nipple burn. But does hold on to sweat compared to my other running shirts.

HiBye is my third NSB Tshirt--my wife has threatened a temporary restraining order to keep me from purchasing more! I've raved about the technical design of this shirt in other reviews (cut, comfort, material and style are all top notch). This is the first one that I've received a lot of comments on due to the simple, but fun tagline. The colors (Mash version) are understated and cool. Looking forward to wearing this one for a long time, both casually and on runs where the dew point is less than 70+ ?
