Product Description
The Union Source sits at the forgiving end of the Lab lineup, built for riders who want genuine high-performance hardware without the aggressive edge of the Source FC or Source Pro. A Duraflex CB baseplate with Direct Connect System keeps you locked to the board with near-zero stack height, while the eco-conscious Duraflex Blue highback wraps your heel with a progressive, supportive feel. For all-mountain riders who demand real response without sacrificing comfort.
Product Details
| Baseplate | S10 Halo Duraflex CB w/ Duraflex CB Core: Union's highest-fiberglass-content nylon in a Halo frame with an integrated Duraflex CB core. Lighter, stiffer, and more responsive than Duraflex ST. Reduced baseplate height maximizes board connection and positions this as Union's lightest baseplate design. |
| Bushing | Hi-Flex HP EVA: Hot-press EVA engineered for high performance. Delivers consistent cushioning, shock absorption, and responsive rebound underfoot. Reduced volume design retains its shape over time. Exclusive to Union bindings. |
| Footbed | Non-Stick HP EVA: Closed-cell finish provides 100% waterproof and ice-proof protection with added dampening and shock absorption underfoot. |
| Highback | S18 Source Duraflex Blue: Asymmetrical freeride wrap design in Duraflex Blue, Union's eco-conscious nylon made from 90% sustainable raw materials, audited by ISCC and TĂśV NORD. More forgiving feel compared to the Source FC and Source Pro. Integrated 3-Stage Forward Lean Adjustment. |
| Forward Lean | Integrated 3-Stage: Three-stage forward lean adjustment built directly into the highback construction for tool-free customization. |
| Heelcup | Extruded 3D Aluminum: Durable and lightweight construction for precise heel hold and stability. |
| Ankle Strap | Hybrid 2.0 w/ TPE Core: TPE core provides cushion and comfort throughout the day. Wider design delivers a more forgiving, supportive fit across boot profiles. |
| Toe Strap | TS 6.0 Dual-Layer UltraGrip: Dual-layer construction conforms to any boot profile for a precise fit. Thermoplastic anti-slip rubber maximizes grip. Multi-positional and compatible with all boots. |
| Strap Adjustment | Pins + Quick-Lock |
| Ratchets | Magnesium S1 w/ Aluminum Base: Union-exclusive magnesium alloy, four times stronger than aluminum at half the weight. Fully protected spring for longer lifespan and optimized spring return. |
| Hardware | Grade 8.8 Steel + Titanium: Highest-grade steel combined with titanium for peak strength, minimal weight, and corrosion resistance in critical binding components. |
| Disk / Mount | Direct Connect System: Ultra-lightweight mounting using two screws and two washers (no disk). Reduces baseplate height for maximum board connection and delivers the fastest possible edge-to-edge energy transfer. 4x2 compatible. |
