Black Diamond Highline Stretch Shell Jacket - Men's Ultra Blue, XL

We pack Black Diamond's Highline Stretch Shell all year long whether we're backcountry skiing in winter or alpine climbing in summer. It boasts BD's burliest waterproofing that's plenty breathable for hoofing it on skintracks and trails alike. All of this burliness comes in a thin, packable design that doesn't take up too much space when it's dry and sunny out. Black Diamond also instilled a performance stretch so we can move freely.
