The Union Source FC is an ultra-light, high-performance snowboard binding built for maximum board feel and direct response. Its Direct Connect Mounting System removes the traditional disk, while forged carbon components, an 8/10 flex and low-profile construction deliver precise power transfer for advanced all-mountain, freeride and freestyle riding.
The Union Source FC is built to minimize the distance between rider and snowboard. By removing the traditional mounting disk, lowering the baseplate height, and cutting excess material, Union has developed a binding focused on direct energy transfer, lower weight, and a more immediate connection to the board. For riders looking for a technical, highly responsive setup, the Source FC sits at the sharp end of the category.
At just 1.13 kg, Union positions the Source FC as the lightest snowboard binding ever developed. That low weight is paired with a stated flex of 8/10, putting it firmly in performance territory for riders who want a supportive and precise feel without unnecessary bulk. The overall construction is centered around forged carbon elements and a reduced-profile chassis, giving the binding a distinctly direct character on snow.
The key design point is the Direct Connect Mounting System. Without a standard disk underfoot, the binding sits closer to the board and delivers a more immediate response from body to edge. Combined with the reduced baseplate height, this creates a setup aimed at riders who prioritize board feel, fast input, and clean power transfer across variable terrain and higher-speed riding.
Union also uses Italian-made forged carbon throughout key structural areas of the binding. The S10 Halo Duraflex XC Baseplate w/ FC Core combines a forged carbon core with a Duraflex XC frame, while the 3D Forged Carbon heelcup, S18 Source Forged Carbon highback, and forged carbon footbed continue that lightweight, high-response construction throughout the platform.
In use, the Source FC is positioned broadly across freestyle, all mountain, performance, and freeride categories, making it a strong option for advanced riders who want one binding with a distinctly technical feel. The specification package stays focused, lightweight, and performance-led, with premium hardware and a streamlined strap setup built around reduced weight and efficient support.
