The Defender is specifically designed to endure the physical demands of young amputees. Optimized carbon fiber lay-ups provide flexibility in a design that is robust and virtually maintenance-free so that users can feel confident over a range of high impact activities. Petite adult amputees will also benefit from the small size offering (16-21 cm) and stiffness categories tailored to their low body weight. The Defender provides premium performance in a pint-sized package.
