Stride after stride, over rolling hills and through evergreen forests, the new Slope Runner moves, wicks and breathes. Its seamless body-mapped design allows for optimal performance and next-to-skin comfort on the longest of days, thanks to its differentiated fabric structure. While the entire garment uses a 5.2-oz 77% recycled polyester/23% nylon, the engineered knit is more open in the back, under the arms and down the sides. The shirt is slim and stretchy, with an extended cuff to allow a tapered fit through the forearms. With Polygiene® permanent odor control and miDori® bioSoft for enhanced wicking and softness.
