Designed for tropical fishing and travel, we’ve updated the fabric of Patagonia's Long-Sleeved Sol Patrol® II Shirt to lightweight, quick-drying 2.6-oz 100% polyester (45% recycled) ripstop with 50+ UPF sun protection. This long-sleeved shirt features a double-layer collar that stays put with hidden snaps at the collar points; it can also be flipped up to give the back of the neck some extra coverage against the rays. Cooling mesh fabric at center back and side vents is receptive to any breeze, providing comfort in the most stifling conditions. The two button-through chest pockets are mesh-lined; there’s also an inset zippered pocket on the left chest. Sleeves secure with self-fabric tabs when rolled up; button cuffs.
