Split Pin System – By combining the standard pin system with the Split System baseplate, Union increases the amount of connection between board and binding. Just one pin changes the mode and locks it into place.

Touring Mode – For touring, the binding slides into the climbing cradle and is locked into place with the pin

Quick Flip Heel Ladder

Riding Mode – For riding, the binding slides onto the baseplate which rotates over the center of the board. The pin slides the through the middle of the baseplate for maximum connection.

X-Carb SP1 Base – This revolutionary composite contains a very high amount of pre-blended, blended carbon, resulting in a super light torsionally rigid baseplate, ideal for splitboarding.

Synthetic EVA 3.0 Bushings – Shock absorbing synthetic bushings are durable and an outstanding compliment for the smooth, natural ride of the SP1 base.

Forged Heelcups – The rigidity and strength of FC Heelcups act like a roll cage on a race car - stiffening the entire chassis. The male/female connection with the base provides a seamless response.

Baseplate Stiffness (1 Soft - 10 Stiff) – 9

Exoframe/Air Ankle Straps – All new for 17/18, ExoFrame/Air produces strength and rapid response on the outside, fit and pillowed comfort on the inside.

UltraGrip Toe Straps – Multi-positional options and thermoplastic anti-slip material keeps you locked in and on point - a simplistic, yet highly durable design.

Magnesium 2.0 Ratchets – Four times stronger than aluminum with only half the weight, the Union buckles are built to last. The new 2.0 design is ten percent lighter than the previous versions.

Symmetric Duraflex Highbacks – Designed specifically for touring, Expedition Highbacks feature an adjustable quick-snap forward lean adjuster that goes from tour to riding mode with the flick of your fingers.

Highback Stiffness (1 Soft - 10 Stiff) – 6

Quiver Compliant – If you have a quiver of decks (split and non-split) just mount the Union Split System disc on each one. You can swap the Expedition bindings between each board quickly and efficiently.

Split Disk – Compatible with Voile pattern and 4x2 DIY.

Quick Flad + Ladder – When it's time to switch your bindings to climb mode, the most comfortable option is lowering your forward lean adjuster to decrease the highback angle for the ascent. Featuring just a one-turn adjuster and quick flip ladder these changes happen with minimal effort.
