One jacket. No plan required. No extra layers, no backup, no second-guessing what to pack. The ONE™ Jacket is built to handle changing weather, terrain, and plans—so you can put it on and go. Updated for Fall 2026, the shell fabric has more stretch, a softer feel, and a clean, matte finish. New underarm mesh panels pair with AERO™ KNIT technology to actively vent heat and regulate temperature as conditions shift around you. The fit was refined too — trimmed through the sleeves for a cleaner silhouette that moves easily between environments, without the extra bulk. Cleaner pocket placement and tighter construction — down to the zipper finishes — round out a more polished, consistent feel. Windproof. Breathable. Water-resistant. Warm without the weight. There is only one.
