Quick overview

The Union Atlas Pro is the boosted variant of the 'normal' Atlas. It features the Exoframe 5.0 Ankle strap and TS 4.0 toe strap for maximum comfort and response. The baseplate, highback, and disk cover consist out of a blend of Forged Carbon and Nylon combined to make this the ultimate all-mountain performance binding. Every serious rider wants this binding in his arsenal.



The Duraflex CB is Union's stiffest baseplate with carbon injection Duraflex Nylon. The forged carbon is not only stronger but also lighter than normal carbon. This gives you a binding like no other that is super stiff and reacts quickly.
The Extruded 3D Aluminum Heelcup is designed for optimum heel hold and minimization of drag, Union 3D Extruded Aluminum heelcups are the strongest in the business.

The S14 Duraflex CB Highback is lighter, stiffer and more responsive then previous Atlas highbacks. The forward lean adjuster has been renewed and is now more minimalistic.


  • Baseplate: Stage 7 - Duraflex CB
  • Heelcup: Extruded 3D Aluminium
  • Highback: Atlas Pro- S14 Duraflex CB


The footbed damping is made of Vaporlite HD. This has been upgraded again, with the same level of damping but even more responsiveness than the previous version. This has been applied both in the footbed and padding under the binding. The Vaporlite has a specific non-stick coating to prevent snow from sticking to the binding.

The Forged Carbon disk cover has low weight, adds another layer of dampening and vibration, and makes the binding more responsive.

The Exoframe 5.0 utilizes tri-axial progressive flex for the perfect boot to binding fit and instant power and response when you’re ready to lay down a hard charging, high speed carve. Easily adjust your ankle strap to any boot with the quick snap of the pin adjustment, no tools needed. Just like all Union ankle straps, the Exofame series comes with the safety and security of DuPont™ Hytrel®, so you never miss a day of riding.
Simple, lightweight, durable – The all-new TS 4.0+ toe strap keeps you locked in for the ride down without letting you know it’s there. A new shorter buckle base helps to reduce weight and pressure points. Easily adjust to any boot with the quick snap of the pin adjustment, no tools needed.


  • Bushings: Vaporlite HD, Forged Carbon disk cover
  • Ankle strap: Exoframe 5.0
  • Toestrap: TS 4.0 SL
