It's no wonder the Union Atlas Binding is a favorite of all-terrain killer, Torstein Horgmo. Lightweight, responsive, and gimmick-free, these bindings waste no space on useless bells and whistles, and 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. When you're a rider with a wider stance, the Canted Gas Pedals on the Atlas supply extra leverage for ollie power, as well as allow the ankle and knee joints to be aligned, thus alleviating pain.

The Atlas highback eliminates highback bite for improved comfort and is cored-out to minimize weight without sacrificing response; plus, Vaporlite (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 Duraflex ST Atlas baseplate makes minimal contact with your board to eliminate dead zones in the board's flex beneath your feet. The SonicFuse ankle strap provides a secure and responsive fit without creating painful pressure points, and the toe strap is low-profile and cored-out to wrap around the front of your boot for a comfy and secure fit.

Rides great but there's some flaws

  • Familiarity: I've used it several times

Pro's: Rides great, very responsive on the mountain, very comfortable.

Cons: The fit is small, I have Rome 11.5 Explorer boots and bought the L/XL bindings, but these barely fit. All the straps and settings are maxed out and the straps barely reach. The front strap is on the last hole so then the strap doesn't reach the guide on top rubber piece so the toe strap ends up flapping around all over the place, makes it a pain to put on and also it will go under the board when skating to the lift chair.

The ankle strap, buckle hardware has to be maxed out and it barely fits, its kind of difficult to get it started

The high back has three holes for adjustment, but you cannot use the first hole, the high back will jam into the heel cup. So makes you wonder what are the three holes for if you can't use them? did they mess up the design, not test it or just recycle parts from other bindings in their line up?

You cannot slide the heel cup all the way back because even-though there are three holes in the base, there's only one hole in the heel cup

All these problems showed because I was trying to get my boots farther back into the binding with moving the ankle strap to back to give more length on the angle strap so it would fit without being in the last hole.

The toe strap will slip off sometimes when riding .

The ratchet buckle has a spring with the sharp edge exposed, at the end of the day my fingers were a bloody mess and looked like hamburger. Definitely a design flaw and safety issue. Wear your gloves, but they will get cut up.

Poorly engineered, poorly designed

  • Familiarity: I've put it through the wringer

These bindings came highly recommended as a replacement for an older pair of Freestyles, and after using them for a season I can say I'm disappointed.

first, the fitting is terrible - I opted for the L/XL, and with a pair of Burton Rampant kicks (12s) I had to adjust the straps to the longest setting, which makes them flop more then Manu Ginobili in the last two minutes of a championship game - second, the build quality is poor: a single tree run in good snow and the metal base was all jacked up, and the little plastic guide that keeps the toe strap inline broke (on BOTH bindings). And while the thumb screw adjusters are cool, they feel super filmsy and will probably break/bend at some point. Performance wise, they're ok - about on par with a pair of Cartel's (which are better designed). If you ride blue groomers all day then you'll probably love these, otherwise stick with Ride or Burton: these are going on KSL, for cheap. Real cheap.

Solid bindings

  • Familiarity: I've put it through the wringer

Like other reviews have stated this is a very well built, solid product. It does what it should, which is hold my feet to my board no matter the conditions or terrain.

I read a review on a different site that claimed to have issues with the toe strap slipping off but I haven't had this happen. The grippy/stretchy material on the toe actually holds better than some previous bindings I've used.

Agreed that the sizing chart could be misleading. I have a smaller boot at mens size 8 and bought M/L and am pretty much maxed out on all the straps.

Only downside is that they are already showing signs of wear and tear as heelcup has some chips and dings and foam around the highback is starting to peel. This is after about 30 days of use.

Overall a very solid product with a lifetime warranty on most of the breakable pieces. Can't ask for much more than that.

Shreds the pow!

  • Familiarity: I've used it several times

I have used this binding off jumps, on groomers, in powder and in tight woods and I haven't been disappointed yet. I did have to send mine back though because a 10.5 wouldn't fit the M/L like the chart said it would.

Incorrect sizing/conversion

  • Familiarity: I returned this product before using it

These bindings rock but now I have to buy elsewhere because of RMA for inadequate sizing and now a lack of availability. Plus I had to pay additional shipping for the returned item because I don't have a printer. Take the $6.99 return shipping offer if you have to return.

FYI, these bindings are as squeaky as my dog's toy.

Love em

  • Familiarity: I've put it through the wringer

I've been on a pair of Union Force's the last few seasons, which were awesome, but decided to try out the Atlas bindings this year. After about ten days on these things i'm sold. Great all-mountain bindings; the medium stiffness and canting makes for a very responsive ride without feeling rigid. The straps can be adjusted quickly without a tool, a great feature. I'm a 10.5 and got the L/XL which is currently set to the smallest setting and they fit great.

Great bindings, watch your sizing

  • Familiarity: I've used it several times

These are great bindings, I use these for trees, groomers, pow, and jumps. Awesome canting, highback, cushioning, the works.

Watch your sizing because I wear a size 9.5 in thirty-two boots and I have absolutely everything maxed out on the M/L. The stated size range seems to be dependent on boot brands. Strapping in is pretty difficult and I feel like the straps are to short. If I could go back, I'd definitely buy the L/XL. Other than that, I highly recommend these.

Edit: be sure to check your screws each morning...I had one of the ankle straps come off the last time I was on top of the mountain. Luckily, I didn't lose any parts and I had a screwdriver on me.

New and Improved

  • Familiarity: I've used it several times

I have ridden Union for 5 years now and have always been really happy with the performance, comfort and overall experience with these bindings. Three years ago I fell in love with the Atlas and pretty much had decided I would never ride anything else. And then they took it away!! Well its back and better than ever. Asymmetrical waffled high back, canted foot bed and super cush ankle strap paired up with the NEW ULTRAgrip toe strap!? It's gonna be a good season...

Yes!!! The Atlas is back. After a years absence in the Union line, the Atlas is back with an all new high back and canting. This binding is team favorite. If you are considering a Force, but are on the lighter side or just like a little softer baseplate, the Atlas is perfect. With all new straps and mellow canting underfoot, the Atlas is one of the most comfortable bindings in the game. The asymmetrical waffle highjack is light and supportive against the heel loop but is torsionally flexible for grabs.
The Atlas is a staple in the Union Binding collection.


I'm with Big Jim. Union's website says the Atlas highback and baseplate are slightly stiffer than the Force's, but you seem to be saying the opposite. I'm interested in which ever's stiffer for my all mountain board.
