In-depth Tech Specs:

• EXP4 Highback - Designed for longer tours and bigger backcountry lines. The EXP4 highback features 15% more fiberglass than our standard EXP3 Duraflex highback. This stiffer new asymmetrical highback shape offers more support on long traverses and quicker edge-to-edge power for the ride down.
• Exoframe 5.0 Ankle Strap - The Exoframe 5.0 ankle strap 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, with no tools needed.
• 4.0 w/pin Toe Strap - TS 4.0+ toe straps keep you locked in for the ride down without letting you know they're there. A new shorter buckle base helps to reduce weight and pressure points. Easily adjust to any boot with the quick turn of a tool-less adjuster.
• Integrated Climbing Bar - Fast and easy. For help on steep climbs, flip the built-in climbing bar down with the end of your touring pole.
• SP3 Duraflex CB Baseplate - It's easy to enjoy the ride down when your splitboard bindings ride like your regular bindings. The SP3 Duraflex CB baseplate is the key ingredient for the best ride feel on the split-board market today.
• Dual Lock System - Simply rotate the binding into place, push the rear lever down, and you're ready to ride. Union's dual lock system is the future of splitboard binding technology.
