The Men's Arc'teryx Skyline Short-Sleeve Button-Up Shirt is a modern shirt for a clean look in the city. Designed for the heat of summer, the Diem fabric is made with recycled polyester that is sustainable as well as cool against the skin. In the office, airport travel with the boss, and even off-hours hikes, this shirt will wick sweat, dry quickly, and remain breathable without showing a wrinkle.
