On rugged cliffs and rocky trails the weather can change rapidly when you're out in the mountains you need a jacket you can rely on. That is why Jack Wolfskin designed the Mens ExoLight Jacket to offer the performance of a hardshell with the comfort of a softshell, so it's perfect for ambitious trips where both are required. On steep uphill sections when you start to sweat, the jacket's softshell characteristics really kick in. It is highly breathable and has a soft reverse side that feels pleasant even when worn next to the skin. And the pit zips further ventilate the skin. You'll appreciate the fabric's highly effective stretch performance when using trekking poles or making big reaches. And when you're carrying a pack, you'll still be able to access your GPS and other small items stashed in the hip pockets. They're raised up high so the waist belt doesn't cover them.
