When the forecast calls for brutal cold and relentless rain, the Patagonia Tres 3-in-1 Parka delivers three layers of protection in one smartly designed system. This men's winter parka transforms from a waterproof breathable shell to an insulated jacket or full winter parka with a simple zip, giving you the flexibility to adapt as conditions change throughout your day on the trails or at the worksite. The H2No® Performance Standard shell blocks out driving rain and wind, while the removable inner jacket packed with 700-fill-power recycled down provides serious warmth when temperatures drop. Built with a regular fit that layers comfortably over your favorite fleece, this sustainable outerwear choice proves that doing right by the planet doesn't mean compromising on performance – whether you're hiking through a winter storm or tackling another day at the job site, the Tres has your back with reliable, versatile protection that adapts as fast as the weather changes.
