Bless Up Trail Button UpThere's an old adage that says if you look good, you run good. Challenge accepted. The Bless Up Trail is our technical button up, tailored to both perform and look good at the highest level. Its main benefit lies in the breathable microperforated fabric that stretches and maintains its durability. Designed with a relaxed collar and straight bottom hem, it dumps heat and keeps you cooler than cool.
