Patagonia Men’s Long-Sleeved Sol Patrol II Shirt. In theory, chasing Indonesian surf and bonefish for weeks on end is like going to heaven; in practice, it’s really damn hot. To make sure you’re covered, the Sol Patrol® Shirt is made of lightweight, quick-drying polyester ripstop with 30-UPF sun protection. This long-sleeved shirt features a double-layer collar that stays put with hidden snaps at the collar points but can also stand up for extra protection against the rays. Cooling mesh (center back) and side air vents are receptive to any breeze, providing comfort in a wide array of circumstances. Two button-through chest pockets are lined with mesh; there’s also an inset zippered pocket on the left.
