"The Kastle MX78 is designed for the skiers that want the one ski quiver. With the 78mm waist width, the MX78 is responsive and lively on groomers but provides solid stability in powder and variable off piste conditions. Kastles proprietary Hollowtech technology ensures a smooth ride and consistent edge tracking. Hollowtech is the evolution of a 20 year old Kastle innovation. The tip of each ski is milled out in an oval shape, leaving just a layer of opaque fiberglass. Hollowtech reduces the weight of each ski shovel by 15 percent. This decrease in mass helps the ski minimize vibrations and hold an edge more precisely. Kastle Total Integration optimizes the ski, binding and boot interface with an innovative component design. Our overall objective is to efficiently translate all of a skiers energy to the skis and create even pressure distribution along the skis entire edge."
