* Design drives evolution. We took an urban necessity, the classic button-down shirt, and elevated it with technical performance, sustainable materials, and cleaner lines. Light, breathable and quick drying, the Skyline Shirt LS wicks moisture and stays cool. Stretch and articulation form the fit and give you freedom to move. A zippered chest pocket secures smartphone or passport, the placket's hidden snap front gives it its distinct style, and the soft Diem fabric is made from 100% recycled polyester.
