This lightweight rain jacket is designed specifically for trail running, with active venting, a deployable hood, and waterproof/breathable fabric with a high-texture backing that makes it comfortable to wear during aerobic activity. Rain, sleet, blowing snow - whether it's Mont Blanc or the Sierra, when running in dynamic environments, a waterproof running jacket is mandatory equipment. Seam-taped and breathable, Patagonia's Storm Racer Jacket is made from 100% nylon ripstop with a DWR (durable water repellent) finish. Inside, high-textured backing keeps the jacket from clinging to skin, while underarm zippers and back vents facilitate air flow. Single-pull adjustable hood stows in collar, secured with lightweight snaps. Knit collar lining adds comfort and wicks moisture. Zipper pocket on inner left chest, with reflective logo on left chest and center back. Elastic at wrists and single-pull adjustable drawcord at hem keep out drafts.
