Union Atlas Step On
Fast in, fast out — total control. The all-new Union Atlas Step On® pairs the proven convenience of the Step On® Instant Connection™ System with Union's most trusted all-mountain platform. Step in to engage, pull the release lever and twist to exit. No straps, no fumbling, no lost minutes at the top of the run.
Built on a brand-new Duraflex CB baseplate and matched to a custom Step On® highback, the Atlas Step On® delivers instant edge-to-edge response with a clean, strap-free profile. You get every benefit of auto entry without giving up the flex, feel, or legendary durability that made the Atlas a staple. Union is the only licensing partner that develops and produces its own Step On® bindings entirely in-house.
Best for: Upper-intermediate to expert riders who want the speed and simplicity of Step On® with the power and precision of Union's flagship all-mountain binding.
