"What Our Gearhead® Experts Are Saying:""I've been wearing the Columbia Silver Ridge IV Ball Cap on every sweaty summer hike this season and it has genuinely changed how comfortable I feel on long exposed ridgelines. The laser-cut venting makes a noticeable difference when the sun is overhead and there's no shade in sight, and the Omni-Wick fabric keeps the sweatband from turning into a soggy mess by mile three.""Most hats are just shade. The Columbia Silver Ridge IV Ball Cap is shade, sweat management, sun protection, and ventilation all stitched into one lightweight package that you'll forget you're wearing until you realize how comfortable you are three miles into an exposed ridge walk. Columbia loaded this one with genuine trail technology rather than just a brim and a logo. The nylon and elastane shell carries Omni-Shade Broad Spectrum UPF 50 to block a wide range of UVA and UVB rays, while Omni-Wick construction pulls moisture away from your skin and pushes it to the surface to evaporate quickly. Omni-Shield repellency turns away light rain and resists stains so an unexpected drizzle or a trail snack mishap doesn't ruin the look. Laser-cut venting keeps air moving through the cap when the trail steepens and the effort climbs, and the hook-and-loop closure at the back adjusts quickly for a clean, secure fit wherever the day takes you."
