"What Our Gearhead® Experts Are Saying:""This short-sleeve version is my warm-weather staple. The UPF 100 is hard to beat, and the mesh lining and vents actually keep me cooler than a T-shirt when the sun is strong. It dries fast, breathes well, and the pockets are super practical for travel or trail use.""When the sun is unrelenting and the air’s thick with heat, we grab the Columbia Silver Ridge Utility II Short-Sleeve Shirt. It’s built with Omni-SHADE™ UPF 100 for maximum sun defense, and the Omni-WICK™ fabric works hard to keep us dry when we’re working up a sweat. Designed with mesh lining and venting, it delivers dependable airflow through the hottest trail days or travel stops. The fit is easy-moving and the features are made to be used—hook-and-loop chest pockets, an interior locker loop, and drainage holes that come in handy when things get damp. Whether we're spending hours under exposed skies or packing light for a warm-weather trip, this shirt gives us breathable protection without overthinking it."
