The Pinnacle jacket is the next evolution of the Shield Outerwear series. It all starts with the Nanospun 4 way stretch fabric technology, creating micro pores that let air and perspiration out, with high stretch polyester fibers with Nano fluid repellency making for an extremely lightweight wind/waterproof breathable shell. It provides exceptional weather protection with fluid repellency, waterproof seams and zipper, and wind resistance while still providing the comfort of a soft, stretch, and breathable fabric.
