The Gramicci Shell Jet Cap is made of Active Shell material, a water-resistant material that is suitable not just for town but also for water play in the lake or ocean. Apart from being water-repellent, it also blocks wind, making it a good general-use material suitable for outerwear that can handle sudden rain or wind during transitions between seasons. It all started in California in the 1970s, when a new generation of free-spirited rock-climbers known as the Stonemasters took residency at Yosemite National Park, pioneering a new way of climbing—with a strong focus on speed and style. These new methods required a new uniform, and whilst painter pants and army surplus gear worked to a point—flexibility was needed. Mike Graham, a Stonemaster with a keen eye for design, set about creating the first true climbing shorts. Since 1982 Gramicci has been making functional clothing for life in the great outdoors. Built for movement, and loved by countless cultural movements—what started out in a garage in Ventura, California has traveled to the streets of Tokyo and beyond.
