Performing Through Lightness:

Our foundation, our roots. ATK took its first steps in this industry by developing lightweight race bindings, and now, as then, lightness is key to achieving what athletes crave: speed. Therefore, it's easy to understand why “performance through lightness” has been the mantra that has accompanied ATK's growth in its early years.

As our role in the ski mountaineering universe started to evolve, we needed some stabilization because it's easy to lose control during a phase of growth, just as it is easy to get caught up in the events. That's why we decided to keep our roots stable, not changing our approach to the activity, and ultimately not getting in our own way.

In fact, as we expanded our catalogue to include the speed touring, touring, and free touring categories, we remained steadfast in our commitment to enabling an ever-wider range of ski mountaineers to achieve performance through lightness.

Durability:

Crafted from high-quality materials and engineered to withstand the rigors of backcountry skiing, the SL World Cup Lightweight offers exceptional durability and reliability. The carefully machined components and thoughtful construction ensure longevity to this tech binding, providing peace of mind during your most demanding adventures.
