Moving fast through the woods, a quick jump over the stream & you're off up the mountainside. When you're trail running & speed hiking you always give it max power. No matter what the weather. The Mens Mountain Pass Jacket from Jack Wolfskin protects you from rain & wind every step of the way. This weatherproof shell jacket is made for fast-paced endurance sports. It is very light, very waterproof & extremely breathable. So it's great when you work up a sweat pounding up those steep trails. & for an extra blast of fresh air, just open up the pit zips. If the weather improves & you no longer need it, it packs down small & can be stashed neatly in your pack. & thanks to the super light fabric, the whole thing weighs little more than 300 grams.
