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
Duraflex CB Highback

15% Lighter than
standard Union nylon highbacks.

The S18 Source Pro highback is built with Duraflex CB nylon for a perfect balance of strength, responsiveness, and light weight. 15% lighter than standard Duraflex nylon and engineered for precise edge-to-edge control.

3D Aluminum Heelcup

Designed for optimal heel hold and reduced drag, Union’s 3D Aluminum Heelcups are lightweight and built to stand the test of time. Backed by a lifetime warranty.

Hybrid 2.0 Ankle Strap

The Hybrid 2.0 ankle strap features a unique V-cut design that flexes naturally with your boot, allowing for powerful forward lean without pressure points. Engineered for light-weight perfor- mance and built to last, it delivers the perfect balance of support and comfort. Trusted by the Union team, the Hybrid 2.0 has quickly earned its place as a go-to favorite on everything from park laps to backcountry lines.

TS 6.0 Toe Strap

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.

Duraflex Blue
