Riding Category
Freestyle Rating: Freestyle bindings are designed for riders looking for the ultimate freedom, comfort and that “loose truck” feel. These bindings are generally best suited for riding park or riders looking for a more soft and surfy board feel.

All Mountain Rating: All Mountain bindings are generally mid-flexing and built to handle all terrain and all riding styles.

Performance Rating: Performance bindings are stiffer, provide instant edge-to-edge response, and the most stable board connection possible. Performance bindings are generally best suited for high speed carving or ridding steep technical terrain.

Binding Flex
Union Bindings come in a variety of flex ratings. The baseplate, highback, straps, bushing and disk all have different stiffnesses to help give a specific ride feel and function. Softer flexing bindings are generally used for more surfy or freestyle riding, while stiffer bindings are generally used for more hard charging and responsive freeriding.

Overall Flex - 8/10

SpecificationsDirect 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

Union’s Lightest Baseplate Ever
+ Connection Point

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

Extremely Lightweight + Responsive
Instant Edge-To-Edge Connection
Reduced Baseplate Height

The 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

Cushioning and Shock Absorption
+ Volume Reduction

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

40% Lighter than
standard Union nylon highbacks.

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.

Duraflex Blue

Union Binding Company is proud to partner with Envalior to introduce our most eco-conscious nylon to date. This new material is a member of the Envalior sustainable product family, attributed with a remarkable 90% of sustainable raw materials, based on a mass balance approach. In addition to being more sustainable than traditional plastics, this material has passed all of Union’s in-house quality control tests for strength, durability in cold temperatures and product lifecycle.
