Union 2026 Source Pro Binding

The Union Source Pro Binding is engineered for riders who demand responsiveness without compromise.

The dual-layer baseplate delivers stiff, snappy energy transfer, while Hi-Flex EVA bushings absorb impacts and vibrations smoothly. Duraflex CB Halo framing balances strength with featherlight construction, and the streamlined Phantom Slim ankle strap paired with the TS 6.0 toe strap keeps things comfortable and clutter-free. Get closer to your board, feel every edge, and ride with precision control that matches your ambition.

Binding Type: All Mountain

Flex: 8/10 (Stiff)

Board Compatibility: Direct Connect Mounting System, 4x2 patterns ONLY

The Union Source Pro introduces a refined approach to binding integration through its Direct Connect Mounting System. By eliminating the traditional disk and securing the baseplate directly to your snowboard with minimal hardware, this system establishes a more immediate connection between rider and board. The result is enhanced responsiveness and reduced overall weight, delivering a more efficient energy transfer and a purer riding experience for discerning snowboarders.

Baseplate: Stage 10 Halo Duraflex XB, Two Layer Baseplate Construction

The Stage 10 Halo Duraflex XB is the lightest baseplate Union has ever produced, engineered to meet the brands demanding strength to weight standards while delivering the durability Union is known for. This frame serves as the hub of the binding, linking the baseplate core, bushing, heelcup, and both straps into one system. Created from partially sustainable carbon injected Duraflex CB nylon, the baseplate is strong and responsive with reduced environmental footprint.

Forged Carbon DCS Baseplate Core:

The new Forged Carbon DCS Baseplate Core is exceptionally stiff, incredibly light, and built for maximum response. Union reduced the overall baseplate height by 10%, putting you closer to the topsheet for a more connected ride. This core delivers the fastest energy transfer Union has ever produced, thanks to their exclusive forged carbon construction.

Highback: S18 Source FC Highback

The S18 Source FC Highback is a Forged Carbon highback making it 40% lighter and offering more response than traditional highbacks.

Buckles: Magnesium S1 w/ Aluminium Base

The Magnesium S1 ratchet has a fully integrated spring which is protected from the harsh outside elements and provides you with Union's best ratchet to date. It has a longer life span and better spring return.

Straps: Phantom Slim Ankle Strap + TS 6.0 Toe Strap

The Phantom Slim Ankle Strap is25% lighter than Union’s standard Exoframe 4.0 Ankle Strap and delivers the same comfort in a sleeker, lighter package. Featuring a smaller ratchet, a compact ladder, and a streamlined design, it reduces weight and materials without compromising performance.

Separating the exterior toe strap frame and interior rubber grip allows the rubber grip to form fit perfectly to any boot shape on the market today, while a new more integrated toe connector gives the the binding a more finished overall look.

Cushioning: Hi-Flex EVA Bushing

More durable and better cushioned than standard thermoformed EVA, Hi-Flex EVA bushings add an extra layer of shock absorption and vibration dampening that won’t pack out or lose shape over time. They keep your ride smoother, your joints happier, and your feet more comfortable. The new reduced-volume design also brings you closer to the topsheet for a more precise, responsive feel.

Forged Carbon Heelcup: This lightweight and response binding heelcup is 45% lighter and stronger than the standard extruded aluminium, while staying just as strong.

Integrated Three Stage Forward Lean Adjuster: Quickly and easily adjust your forward lean with a #2 Phillips screwdriver.

Grade 8.8 Steel + Titanium Hardware: Union ensure their hardware is reliable by using the strongest steel and titanium available on the market.

Titanium Screw Strap Adjustment: Titanium screws are lightweight, strong, and easy to adjust.
