Royal Robbins' Desert Pucker Shirt for Men is a cool, casual shirt for days at the beach or afternoons in the backcountry. Royal Robbins' woven polynosic rayon and polyester blend offers a great combination of technical features in a comfortable package. It's very soft and has a great drape that maintains its shape while hiking. And the shirt's pucker weave is naturally wrinkle-resistant and packable, which makes it a good option for travel.
