Patagonia Capilene Cool Sun shirt l/s

The Patagonia Cap Cool Sun Shirt delivers essential sun protection for high-output mountain activities. Crafted from Capilene Cool Lightweight 100% recycled polyester, this technical long-sleeve shirt provides UPF 50+ protection against harmful UV rays—critical during extended alpine traverses, glacier crossings, or exposed ridge hikes.

Its exceptional breathability and active moisture management system wicks sweat away from your skin, keeping you dry even during aerobic efforts. The ultralight, fast-drying fabric makes it ideal for technical layering or as a standalone piece on hot days. HeiQ Fresh antimicrobial treatment reduces odor during multi-day treks or adventure travel, when washing isn't always an option.

The comfortable fit and movement-oriented cut make it versatile for mountaineering, hiking, trail running, or simply exploring under the sun. Made with NetPlus certified recycled polyester from reclaimed fishing nets, it reflects Patagonia's commitment to environmental responsibility without compromising performance.

Whether you're pushing hard on a sun-baked approach or traveling through tropical climates, the Cap Cool Sun Shirt provides reliable protection and comfort when you need it most.
