Union Source FC – the lightest snowboard bindings ever created
Union Source FC represents the pinnacle of binding engineering — the stiffest, most reactive and the lightest snowboard bindings Union has ever built. Featuring the all-new Direct Connect mounting system, a forged carbon baseplate, heelcup and highback made in Italy, and a drastically reduced binding height, Source FC delivers the closest, most direct connection to your snowboard in history.
Weight: 540 g (per binding, size M)
Main Features
- The lightest snowboard bindings ever produced
- New Direct Connect system – no disk, instant response, lower weight
- Forged Carbon baseplate core, heelcup and highback – made in Italy
- Lower baseplate profile for the fastest energy transfer possible
Product Description
Union Source FC is a true breakthrough in binding design. By removing the traditional mounting disk, lowering the baseplate height by 10% and using fully forged carbon components, Union achieved unmatched responsiveness and precision. The dual-layer baseplate construction maximizes control and stability, while the ultralight straps and magnesium hardware further reduce weight. This is the ultimate choice for riders who demand instantaneous feedback and a perfectly direct board feel.

Technologies
Direct Connect
A revolutionary no-disk mounting system. Provides instant response, a stiffer interface and significantly reduced weight. Uses only two screws for board connection.
Two-Layer Baseplate Construction
A unique dual-layer platform — Core and Frame — allowing each layer to be engineered with different materials and flex characteristics for unmatched precision and board feel.
Forged Carbon DCS Baseplate Core
An ultralight, extremely stiff forged-carbon core, 10% lower in height for the fastest energy transfer ever achieved in a Union binding.
S10 Halo Duraflex XB Frame
The lightest baseplate frame Union has ever produced — carbon-reinforced, durable and engineered to connect the core with the bushing, heelcup and straps.
Hi-Flex EVA Bushing
More durable and more shock-absorbing than traditional EVA. Maintains its shape, reduces fatigue and brings the rider closer to the board.
S18 Source FC Highback
A forged carbon highback — 40% lighter than standard nylon models, ultra-responsive and built in Italy for maximum precision.
Forged Carbon Heelcup
45% lighter than aluminum and built to last. This forged-carbon heelcup is ultralight, exceptionally stiff and backed by Union’s lifetime warranty.
Phantom Slim & TS 6.0 Straps
The lightest straps ever produced by Union. The Phantom Slim ankle strap provides full support at minimal weight, while the TS 6.0 toe strap naturally adapts to any boot shape without pressure points.
