Our Patagonia Men's Short-Sleeved Self-Guided Sun Shirt blends quick-dry on-the-water/trail performance with 40+ UPF sun protection for all-day comfort.

• Comfortable, lightweight, quick-drying 100% recycled polyester plain weave with 40+ UPF sun protection and mechanical stretch for easy movement.
• Pocket Details.
• Two vertical chest pockets with corrosion-resistant zippers fit fly boxes; two button-closure chest pockets keep essentials close, and there's a hidden tool dock under the right-chest pocket flap.
• Collar Details.
• Double-layer collar converts to a stand-up collar for additional sun protection, and hidden snaps at the collar points eliminate flapping in the wind.
• Stay-Cool Venting.
• Open venting across the back and shoulders increases airflow for cooling comfort in steamy weather.
• Fit Details.
• Extended hem stays in place while casting, rowing or hiking to enhance comfort and sun protection, and the shirt won't bunch or ride up when worn with hip packs.
• Lens Cleaner.
