Perfect for all-day wear, the Cambio Button Up is a put-together travel shirt made from an anti-static, anti-odor blend of 86% recycled polyester and 14% spandex. Easy to dress up or down, this shirt is the ideal base for mix-and-match, on-the-road packing. Featuring a passport compatible external chest pocket, the Cambio also sports a Polygiene® anti-odor finish that keeps it smelling (and feeling) fresh between sporadic washes.
