Button down some tech fabric with Arc'teryx Short Sleeve Adventus Comp Shirt. Its clean style lends this collared shirt to mid afternoon golf games, casual hikes, and everyday use. The smart Diem polyester is a super lightweight textile that dries quickly and stretches to keep up with your active day. In the underarms you'll find Phasic SL, one of the most hydrophobic knits on the market. It's composed of many polyester yarns that wick moisture laterally to dry quickly and polypropelene fibers with encapsulated silver ions that control odor for hours on end. A full snap front closure, zippered chest pocket, and laminated hem add to the shirt's clean look, while the UPF 50 rating means it's not the end of the world if you forget your sunscreen at home.
