The ATK Hy Free 13 binding redefines what's possible when you refuse to compromise between resort performance and backcountry efficiency. At just 675g, this precision-engineered marvel delivers true alpine-level downhill performance through its flat boot positioning system, eliminating the forward lean that plagues traditional pin bindings and giving you the confident, powerful descents you'd expect from your favorite resort setup. What sets the Hy Free 13 apart is its unique negative walk mode that drops your heel 18mm below toe level, dramatically reducing calf strain and improving stride efficiency during long ascents—a game-changer when you're grinding out vertical in stiff freeride boots. The automatic-locking HY brake system seamlessly engages during transitions and releases with a simple push, while 22 meticulously machined 7075 aluminum components ensure this lightweight powerhouse can handle everything from charging powder lines to technical mountaineering objectives, making it the ultimate hybrid ski binding for serious freeriders ready to unlock both resort and backcountry terrain.
