Dawn is breaking as you set off, your gaze fixed on the distant peaks. Made in collaboration with the Alpine School Innsbruck (ASI), Jack Wolfskin have developed the lightweight Exolight Pro shell jacket specifically for alpine trekking and mountaineering. The waterproof Texapore O2+ outer fabric has an additional, extremely water repellent Super DWR finish to protect you from the elements - shedding water and thus preventing the outer fabric from becoming saturated. So the jacket keeps you dry. And you stay dry for longer. The fabric is also stretchy and super breathable, so the jacket delivers the freedom of movement and advanced climate comfort you need for long, hard days in the mountains. The special cut is also designed to enhance mobility. With pro standard detailing including pit zips, water resistant zips, and a helmet compatible hood, the Exolight Pro is endorsed by the ASI mountain guides for demanding mountaineering use. And if the temperature drops when you’re above the tree line, there is enough room under the jacket for an insulation layer.
