The lightweight, responsive, and gimmick-free Union Atlas Binding wastes no space on useless bells and whistles???every feature from the Multizone highback to the minimalist baseplate profile to the dual-density padding is fine-tuned to improve response, comfort, and board feel. Dope details like magnesium buckles, multi-position straps, and quick-adjust forward lean give the Atlas a high-end feel without costing you more than you paid for your season pass.

The Atlas highback eliminates highback bite for improved comfort and is cored-out to minimize weight without sacrificing response; plus, injected EVA bushings dampen vibrations for a smooth ride. An extruded 3D aluminum heelcup reduces weight while maintaining strength and stiffness, and the Stage III Atlas baseplate makes minimal contact with your board to eliminate dead zones in the board's flex beneath your feet. The 3D Direct-Connect ankle strap provides a secure and responsive fit without creating painful pressure points, and the Open Toe Strap is low-profile and cored-out to wrap around the front of your boot for a comfy and secure fit.

get the job done and look good too

  • Familiarity: I've put it through the wringer

I switched to toe cap bindings after over 10 years of riding fl*@$ uhhh we'll say step-ins and the union atlas' have successfully converted me back to straps. I'm a big fan of the design and materials, except for the top strap material is more fashionable than durable, after one or two days, there were tears, and gouges all over on it. It still works great, they just look like my roommate chewed on them. the paint job on the magnesium ratchets was also short-lived when it got jibbed by my chair-lift companions edge. All-in-all a great product, but for $240 the materials & finishing need to be improved before I'll give it 5 stars.

Unanswered Question

I wear a size 11 boot (Burton Ambush) with a reduced footprint so it fits in the binding like a size 10. What size should I get?

Would these be a good binding to get for just riding all mountain? I've been looking at bindings because I'm looking to get a new setup next year. I was looking at a pair of Flux PR, would those do well all mountain? I wear a size 11 boot, what size should I get?

What up Jacob,

These have a medium flex so they would be a great binding for riding all terrain. I would recommend going with a M/L in these bindings!

Responded on

Thanks Adam,
I'll definitely keep these on the list for bindings to buy!

K2 UFO US11 in Union Atlas M/L

Put my K2 UFO 11 US (2k14) size boots into girlfriend's Union Atlas M/L size (2k12) to understand what size to order for me (straps were not adjusted).
On my opinion boot looks too big for M/L size of base plate.
Decided to order L/XL bindings, hope they wont be too big.

Responded on

They don't look all too big in the bindings in my opinion. Do your boots have reduced footprint?

Responded on

As I know K2 boots haven't got reduced footprint. They are not too big, just normal.
BTW Union Factory XL fit them pretty good.

Light and Responsive

  • Familiarity: I've put it through the wringer

I used this bindings are 30 times this season. Good for anything you feel like doing. The ratchets are very easy to snap in and out of. The only thing i don't like about them is that sometimes the screws come loose on the straps.

AWESOME binding, TERRIBLE paint job...

  • Familiarity: I've put it through the wringer

These bindings are super sick, responsive, cush and overall great bindings for the money. my only complaint is the paint can't take any sort of a bump or contact...

  • Familiarity: I've used it once or twice and have initial impressions

Its a pretty sweet feeling binding with quite a bit of response to it. Love the impact comfort it provides. I went boarding just the other day in them and cased it on a landing which I was expecting to hurt WAYYY more, and out jupmed another landing which was on flat ground once again, and I totally felt a difference in comparison to Burton Cartel bindings I have had in the past.

It's more of a Mid range back, which I think isn't as responsive as high backs, but the tech that runs along with this base plate is well worth the sacrifice of having a high back.

I wear DC Judge men size 8 boots, should I get the S/M or M/L?

Responded on

I wear size 9 boots with my Unions and feel like the Medium/Large would be way too large if I were in a smaller boot. I suggest sticking with the Small/Mediums for you boots.

Great binding

  • Familiarity: I've put it through the wringer

I have ridden these bindings for most of the current season and I am a big fan. I upgraded fro the Union Contact and I am happy I did. The Atlas is a bit lighter and lower volume so the entire setup feels nice and compact. The binding is nice and stiff and the ratchets are superior to those on my old contacts (about three years old). I have a size 11 boot and went with the XL which fits my boots nearly perfectly. The multiple foot bed options allow me to really dial-in the coverage on my toes to enable a responsive toe-side edge.

for a size 9.5 boot i ride the Burton rampant, what setting would have your heel cup on 0,1,2 i'm new to union bindings so i need help.

Best Answer Responded on

For me personally it took me about a day to make adjustments out on the mountain to get them correct. It takes a little trial and error. I would just set them up at your house and get a good feel and work from there.

I'm guessing you purchased the larges, so I would probably start off at 0 because me at size 12 i am at 1 (middle setting). I started off at to longest setting but found I like it in the middle for easy and quick strap on.

Pretty Solid So Far

  • Familiarity: I've used it several times

First thing I noticed when I put these on my board was how the bindings brought out the best of my board. With the baseplate and the connecting points of the bindings, I suddenly had a lot more wobble and dexterity than I had with my older bindings. It was a whole new board. It really brought out the rocker and camber profile and I could actually really start to feel it, even before I ever strapped in.

I would give them about a 4-5 in stiffness personally. Really nice feel and flexibility, but not too much with the symmetric highback. The symmetric high back starts off stiff around the upper ankle area and gets progressively softer around the lower calf. I find myself being able to lean forward and backwards with a lot more feel while staying firmly connected to the board. Gives me good movement range and also helps going through moguly(not sure if that's a word) snow.

Strapping in is quick and easy with the straps. They seem solidly built to me but commenter below posted that he had issues with these, so I'm still keeping a lookout. Nothing thus far after about 6 uses. The straps hold firm and true and are nicely padded, so quite comfortable. I also like how you can manually adjust the front straps by just pushing down on the strap and moving it forward or backwards for if you either want to use the toe cup or old school style.

All around just a solid binding. Would recommend for anyone intermediate up. Will say I think there are other bindings out there that match up, but nothing that really stands out. Don't think you can really go wrong with these.

Light but rock solid.

  • Familiarity: I've used it several times

Great bindings, incredibly light and solid with a lot of good adjustments available. Check Union's YouTube video on how to set up your bindings for all the adjustments. I've only found two minor quibbles: the white upper strap cloth collects a lot of dirt off my boot and looks dirty, and the heel cups on the XL are kind of narrow for 13/14 boots. That said, they create a totally solid connection with your board, quell vibration and are way better than my old Burton Mission bindings.

Love'em but....

  • Familiarity: I've used it several times

These bindings are perfect, but after riding with these a few times. One of my bindings gave my a huge problem with slipping to the forward notch for traditional toe strapping and I toe cap, which makes it a problem sometimes. The same binding, the high back adjustment fell apart and at first I thought it might have just loosened up from constant strapping in, but it appeared to have come off from the metal threads being too soft and allowing the screw to come out. I haven't contacted Union, but plan on doing so. I've gone to the Mt. with these 4 times before this happened therefore I won't recommend these, especially for what I paid for them.

Such sick binders!

  • Familiarity: I've used it several times

These things are a dream! Bought them in hazard orange and let me tell you, they are bright bright highlighter orange. Most of my friends find me on the mountain now due to these bad boys. Awesome.

They are easy to adjust, easy to get into, comfy and very light weight. I was on Burton Customs before and the vibration and chatter I would feel at high speeds is completely gone. Union makes sick bindings and the Atlas' won't fail you. They are still fun to flex around in the park with, pressing and jibbing now problem. They feel great in the air with landings as well.

Snag up a pair and never worry about if you made the right decision or not.

Light & Responsive bindings!!

  • Familiarity: I've put it through the wringer

I've ridin the Atlas Bindings for the last two years. I rode the Force before that & loved it. The Atlas is a slight step up from the force weighing in a lil lighter & maybe a bit more cumfy too w that wider ankle strap. I've riden all over Colorado & Utah in these binders & havent ever had an issue with them, They are very reliable!! I have a 32 Focus Boa(Best Boot Ever!!) in a sz 9 & I rock a sz M/L Atlas. They are super responsive all over the mtn & very versitile so I use them as my Daily Driver for the most part!!
