Patagonia M's Capilene® Cool Sun Shirt

Built for Long Days Under Open Sky

The Patagonia M's Capilene® Cool Sun Shirt is designed for anglers and outdoor adventurers who spend extended hours exposed to sun, heat, and movement. Whether you're casting across wide rivers or covering miles in alpine terrain, this long-sleeve technical layer delivers breathable comfort and dependable sun protection when it matters most.

Lightweight Sun Protection That Keeps You Cool

Constructed from 100% recycled polyester jersey, the Capilene® Cool Sun Shirt offers 40+ UPF sun protection built directly into the fabric through a single-knit construction that won’t wash out over time. The lightweight material wicks moisture and dries quickly, while a textured interior lifts the fabric slightly off the skin to promote airflow and cooling comfort. Designed for movement, the articulated sleeves and minimal seams reduce friction during active use, while thumb holes extend protection across the backs of the hands.
