The ATK HY 13 Free Binding offers downhill performance on par with alpine bindings in an extremely lightweight package, delivering responsive and precise power transfer to your skis. Its revolutionary feature, in the hybrid bindings category, is the combination of lightness and ease of use.  Merging lightweight design with alpine-grade downhill performance, it enables freeriders to explore without limits. A hybrid binding that is as high-performing on descents as it is enjoyable on ascents. The Hy Free unlocks the true potential of hybrid bindings.

Toe piece:

Alpine performance: The Hy Free delivers the responsiveness, control, and confidence of an alpine binding. The boot sits flat on the ski in ski mode, eliminating the pin-height differential typical of standard PIN bindings for a true downhill experience.

Seamless transitions: Switching between ascent and descent modes is effortless. Simply raise the toe arms for walking or rotate them forward and down for skiing. The intuitive design ensures reliable performance in all conditions with no need for interchangeable parts.

Compatibility: The Hy is compatible with most alpine skiing, ski mountaineering, and freeride boots. Engineered spacers fit between the sliding section of the Anti Friction Device (AFD) and its underlying structure. These spacers ensure proper boot-to-binding contact while accounting for the sole's thickness & provide vibration dampening for each sole type.

Heel piece:

Negative steps: For uphill efficiency, the Hy Free includes a unique “negative” walk mode that allows the boot heel to drop slightly below the toe level. This reduces strain and improves stride efficiency, especially for freeride boots with limited cuff mobility and during long flat approaches.

Walking modes: The Hy also features two heel raisers for easier uphill progress, both activated easily even with the pole.

Hy Brake System: The rear ski brake locks automatically when the heel piece is in walk mode. This means that when the real lever has been pushed fully forward the ski brake can be locked in position with a simple press of the rear paddle. When transitioning to ski mode, it seamlessly unlocks by pushing the rear lever backwards, ensuring hassle-free use.

Durability

The Hy is a masterpiece of minimalist engineering. Weighing only 675g, it offers a remarkable balance between lightness and strength. All of the binding’s structural components (22 per half pair) are crafted from 7075 aluminum, ensuring that every component is both lightweight and incredibly durable.
