Union Source FC Snowboard Binding 2026

Push the limits of performance with the Union Source FC — the lightest, most connected snowboard binding from Union’s 2026 line. Engineered for the rider who demands instant board‑feel and aggressive response, the Source FC features a stripped‑down baseplate, a revolutionary two‑screw “Direct Connect” mounting system, and high‑end forged carbon materials throughout.

Key Features

• Weight‑saving forging: At approximately 540 g per binding (size M), the Source FC slashes weight to deliver exceptional agility.
• Direct Connect mounting: Union replaces the traditional disc with a minimalist two‑screw system, reducing stack height and increasing response. 
• Forged Carbon construction: High‑end carbon materials in the baseplate and highback keep rigidity high while shedding gram‑weight. 
• Precision edge‑to‑edge feel: This binding is built for high‑performance riders carving hard and riding steep terrain — it’s not for the faint of heart. 

Who It’s For

If you’re a dedicated freeride or advanced all‑mountain rider who wants the absolute maximum direct connection between you and your board, the Source FC is built for you. The stiff feel and ultra‑low profile demand precision and commitment, and reward responsiveness like no other binding in the lineup.

Why Choose Source FC?

When every millisecond counts, when you need your board to react instantly, and when you’re not willing to compromise on precision — the Source FC stands apart. By eliminating the traditional mounting disc, bringing your boot closer to the board, and using ultra‑light forged carbon, Union has created a binding that’s as much about feel as it is about tech.

Fit & Sizing

The Source FC comes in sizes XS, S, M, L, XL (depending on region/stock) to fit a wide range of boot sizes — check the size chart before ordering to ensure proper fit.

Note: Because of its ultra‑stiff build and minimal cushioning compared to more forgiving bindings, beginners or casual riders may find this binding too aggressive. For more relaxed riding, consider less aggressive models.
