A convenient and much appreciated part of any outdoor layering kit, the Kuhl Parajax Jacket delivers ultralight protection from wind and light rain whether you're out exploring summits in far-flung mountain ranges or furthering your familiarity with the peaks and valleys closer to home. It's made with Kuhl's Air Blok fabric, a lightweight nylon ripstop that cuts the wind on exposed peaks, but still offers enough air permeability to stay breathable when you're exerting yourself on steep slopes. A partial mesh lining increases breathability and next-to-skin comfort, while a snug adjustable hood and hem ensure that whipping winds stay out. This jacket is also treated with a water-resistant coating that sheds lighter rain and moderate snowfall, preventing you from getting soaked as you scramble for cover when the weather changes. Plus, the entire jacket weighs less than four ounces and packs down into its own front pocket, making it easy to bring along on any adventure and pull out of a pack quickly when you need it.
