Each material and design choice works in harmony to create a luxuriously cushioned ride that feels more like surfing on a cloud than strapping into a binding.

Key Features

Asym Molecular Bushing - More durable and more cushioned than traditional thermoformed EVA, Molecular Bushings act as a suspension system between the baseplate and the boards top sheet, to help reduce vibrations from harsh snow pack. The all-new asymmetrical bushing shape allows for increased freestyle flexibility and natural inward canting while riding

Minimal Base Contact = True Board Flex - Union baseplates are designed to provide supreme strength while minimally interfering with your board's natural flex. Minimal board to binding contact means sweeter response, better board control, and improved durability.


Duraflex ST Highback - Union exclusive Duraflex material was specifically engineered to maintain consistent flex in a wide range of cold temperatures.


Forma X Ankle Strap - Exoframe exterior for instant response, padded interior for all day long foot comfort. Exoframe connector acts as a suspension system for your boots.

Tool-Free Ankle/Toe Strap Adjustments - No screwdrivers needed here. Simply flip the adjusters by hand to fine-tune your fit.

Magnesium S1 Ratchets - When you ride 100+ days a season your ratchets take a beating. 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 integrated spring protected from the harsh outside provide you with Union’s best ratchet to date. Longer life span and better spring return guaranteed.


Size-Proportionate Fiberglass Index - Bigger riders require stiffer bindings. Union proportionally increases the fiberglass content in each size of their bindings so that any rider who straps in will have perfect support.

S11 ASYM Duraflex ST Baseplate - Asymmetrical Baseplate for increased torsional board flex. All-new Astro Washer prevents heelcup slipping. Made with Duraflex ST Nylon.

Extruded 3D Aluminum Heelcups - A new process removes as much excess material as possible in the heelcup to reduce weight while maintaining tried and true strength. Union heelcups undergo an anodizing process reinforcing the already bombproof apparatus with another 30-percent strength. It's serious strength in a streamline package.

Universal 4x2 Channel Compatible Minidisk - Designed to create a minimal contact footprint for even board flex.

Compatible with any traditional 4-hole or 3-hole snowboard mounting inserts, along with Burton snowboards featuring The Channel. You can mount Union Bindings on any board you choose.

Not compatible with 4x4 or with boards featuring powder pack setback insets.

Grade 8.8 Hardware - The strongest steel available on the market - the use of Grade 8.8 represents Union's commitment of delivering the strongest and most reliable bindings on the market today. Top to bottom.

The most commonly used hardware is made from "mild steel" that has a property class of only 4.6. Considering how much stress a binding is put under, Union uses only the strongest steel (featuring a property class of 8.8) on all hardware.


Lifetime Warranty on Baseplate and Heel Cup - Covered under manufacturer lifetime guarantee against breakage of the baseplate or heelcup along with defects in materials or workmanship. This lifetime warranty DOES NOT cover broken bindings due to abuse or neglect, damage caused by any modification done outside the manufacturer's facility, or lost parts due to lack of hardware maintenance.

Highbacks, straps, ratchets and other components are covered under Union's 1 Year Warranty.

Relaxed and surfy yet powerful

Union Ultra Snowboard Bindings - hot red
These are great! I'm basically an all-mountain guy, love sidehits, steeps, and high-speed carving. I wanted to try something looser and more freestyle-oriented than the Union Atlas bindings I've been riding the last few years (and Force before that). I really like the simple clean look with no forward lean adjuster (highback angle feels just slightly less-than the 2 clicks I had on the Atlas). Adjustments were easy to move the heelcup a bit to center my foot, and center the straps over the boot. Different feel from mini-disc isn't distracting. Super easy to boot-in (a pleasant surprise) since the baseplate 'wall' of the binding is relatively low. Highback is totally solid when pushing strong into it. Straps have more flex than the Atlas/exoframe but still powerful when going to toeside, maybe just slightly less instantaneous turn initiation, but that is balanced with more tweakability and playfulness.

I have taken a LONG break from snowoarding, just got into it again this year. Every review pointed toward Union's and I can see why. They are light, responsive, and VERY comfy and stable!

Union Ultra Snowboard Bindings - aqua blue
My son loves this over the flow bindings he’s used to. This is 100 percent better in the park and all around on groomers for him. He just turned 10 and is completely stoked.
