In short

The Union Source FC is what happens when you strip everything back to the essentials. And then rebuild it with carbon and titanium. With a baseplate height lower than its skinny stance and a total weight of just 540g per side, this is the lightest binding Union’s ever made. The Direct Connect system gives an unmatched board feel, and the forged carbon setup transfers every movement with surgical precision. Designed for advanced riders chasing speed, response, and total control. Step in, hold tight, you're in the cockpit now.

In detail

PERFORMANCE

The XB Halo Base Frame is lightest baseplate Union has ever created, while still maintaining the mandatory strength-to-weight ratios needed to pass Union’s strict durability tests. The frame also plays the critical role of connecting the baseplate core, bottom bushing, heelcup, ankle and toe straps together. Made with partially sustainable carbon injected Duraflex XB Nylon.

The Forged Carbon Heelcups strengthen the chassis of your binding and ensure good responsiveness.
The Forged Carbon Highback is one of the lightest and strongest on the market, designed for the most high-end bindings. By incorporating Forged Carbon into the highback, the binding becomes lighter and its responsiveness quicker.

  • Baseplate: Halo Duraflex XB
  • Heelcup: Forged Carbon
  • Highback: Forged Carbon

COMFORT

Hi-Flex EVA bushings act as an additional layer of dampening and shock absorption between you and your snowboard and never loose shape over time. Your knees and feet will thank you.

25% lighter than our standard Exoframe 4.0 Ankle Strap and still just as comfortable. The new Phantom Slim Ankle Strap features a smaller ratchet, smaller ladder, and a new streamlined lightweight ankle strap design to help reduce weight and materials as much as possible. You won’t even notice that it’s there.

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.

  • Bushings: HI-Flex Eva Bushing
  • Ankle strap: Phantom Slim
  • Toestrap: TS 6.0

USE

Union’s all-new Direct Connect System is just that — a direct connection between you and your snowboard. By fully removing the disk from the baseplate, Union has been able to drastically improve the reaction speed between the rider and the snowboard, increase baseplate strength, and simultaneously reduce the overall weight of the binding. Disks are a thing of the past. This all-new mounting system only relies on two screws and two washers to get the job done.

Freezing temps, water damage and constant strapping and unstrapping all play a role in the longevity of a binding ratchet. Lucky for you, the all-new Magnesium 4.0 ratchets are Union’s answer to the elements. A fully intergraded spring protected from the harsh outside provide you with Union’s best ratchet to date. Longer life span and better spring return guaranteed.
