What Our Gearhead® Experts Are Saying: "I wore the Sombra Long-Sleeve Sun Shirt on a 5-day desert backpacking trip and barely noticed it was there. It’s light enough to stay cool under full sun but provides all-day UPF protection and dries super fast. The stretch and fit make it great for everything from paddleboarding to hiking."When the trail heats up or the water calls, we reach for the Cotopaxi Sombra Long-Sleeve Sun Shirt. It’s the kind of top that disappears on the skin but stays in the game when the sun gets intense. Cotopaxi built this shirt for movement—whether we’re trekking ridgelines, paddling lakes, or exploring new coastlines—with airy, breathable fabric that stretches with every reach and step. Constructed from 100% recycled polyester, the Sombra weighs in at just 101gsm and keeps us cool, dry, and odor-free thanks to its Polygiene® anti-odor and wicking finish. Flatlock seams eliminate chafing during extended wear, while the contrast binding at the sleeves and hood adds a subtle pop of style. Thumbholes enhance coverage when we need it most, and the UPF 50+ protection keeps our skin shielded from the harshest rays.
