The super lightweight Cayo Largo II Shirt maintains a cool presence, even under the pressure of a humid, sticky, overheated day. Made with a soft, lightweight and fast-wicking fabric blend of organic cotton, recycled nylon and hemp, it breathes easily, even in stifling heat. Relaxed styling, with a button-front placket and a lie-down collar, travels equally well on a Sierra trail as it does the streets of Florence. Two buttoned pockets and a hidden front-chest zip pocket (sized to fit a U.S. passport of a medium fly box) hold your small essentials securely above the waterline. With a shirttail hem to stay put under a hipbelt.
