The Source FC is made for riders who want to push hard in freeride while maintaining true versatility. Its robust construction, combined with forged heelcups, provides impressive stiffness and responsiveness — perfect for charging down slopes at full speed and linking clean, powerful carving turns. Its classic dual-strap system allows for precise adjustments, delivering optimal control without sacrificing comfort — a rare achievement for a binding of this performance level.
Direct Connect Mounting System
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.
Two Layer Baseplate Construction
A traditional snowboard baseplate is made of a single layer with the same material and stiffness throughout. Union exclusive Two-Layer baseplate construction allows us to have two individual layers: the Core [1] and the Frame [2]. Each layer has the possibility of using a unique material and stiffness to achieve the desired ride feel of the binding.
Duraflex CB Halo Baseplate Frame
The Duraflex CB Halo Baseplate 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 CB Nylon.
Forged Carbon DCS Baseplate Core
he all-new Forged Carbon DCS Baseplate Core is stiff, responsive, and ultra-lightweight. Through extensive rounds of R&D the Union Lab was able to reduce the baseplate height by 10% getting you as close to the topsheet as possible. This baseplate layer allows for the fastest possible transfer of energy from the rider to the snowboard that Union has ever achieved. Made possible by Union exclusive Forged Carbon.
Hi-Flex EVA Bushing
More durable and more cushioned than traditional thermoformed EVA. Hi-Flex EVA bushings act as an additional layer of dampening and shock absorption between you and your snowboard and never lose shape over time. Your knees and feet will thank you. This all-new reduced volume bushing design allows the rider to be as close to the topsheet as possible.
S18 Source Forged Carbon Highback
The S18 Source Forged Carbon highback is 40% lighter than our standard nylon highbacks and extremely responsive edge-to-edge. Made in Italy using Union exclusive Forged Carbon.
Forged Carbon Heelcup
Lightweight, responsive, and made in Italy. Union’s Forged Carbon heelcups are 45% lighter than our standard Extruded Aluminum heelcups and still just as bombproof. Backed by Union’s lifetime warranty guarantee.
Phantom Slim Ankle Strap
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.
TS 6.0 Toe Strap
TS 6.0 toe straps keep you locked in for the ride down without letting you know they're there. A new, shorter buckle base helps to reduce weight and pressure points. Easily adjust to any boot with the quick turn of a lightweight titanium screw. This is the lightest toe strap on the market.
