Lightweight, Multi-Sport Solar Shielding with Premium Climate Management

The Cotopaxi Women's Sombra Long-Sleeve Sun Shirt is an indispensable, ultra-lightweight technical layer engineered to shield you from intense UV exposure during unshaded alpine ridge hikes, high-glare river paddles, and warm-weather travel. Meticulously constructed from a feather-light 100% recycled polyester jersey, this high-performance top offers an exceptional UPF 50+ sun protection rating, effectively blocking 98% of harmful ultraviolet rays. Built to be thrown on comfortably over a summer tank or worn as a standalone layer, the technical weave actively accelerates moisture wicking to pull sweat instantly away from the skin, optimizing evaporative cooling when your heart rate spikes.

Designed to withstand grueling back-to-back travel and trail days, the fabric is treated with a premium Polygiene® anti-odor finish that prevents odor-causing bacterial growth at the fiber level, keeping the shirt thoroughly fresh between washes. The Sombra features a versatile, motion-friendly regular crew neck fit, enhanced with anti-chafing flatlock seams that lay completely flush to eliminate friction hotspots under backpack shoulder straps or life jackets. For extended solar protection across the backs of your hands, the sleeves are finished with integrated, low-profile thumbholes and distinctive contrast binding, combining signature Cotopaxi colorways with reliable outdoor functionality.
