The Union SL Binding strips away all excess weight without making compromises when it comes to comfort, response, and dampening. A fine-tuned flex in the highbacks and baseplate means the SL gives you plenty of power for high-speed heelside slashes, with enough tweakability up top to lock into a nosepress or poke out a big ol' tailgrab.

  • Asym/Symmetrical highback delivers reliable heelside power with an engineered flex pattern for comfort and side-to-side mobility
  • Atlas III baseplate minimizes the contact area on your board's topsheet to minimize the 'dead zone' under your bindings
  • Dual-density bushings under the baseplate dampen impact forces and improve your board's natural flex
  • Magnesium buckles are lighter and stronger than traditional aluminum
  • Open toe straps for secure grip either over the top or around the front of your boots
  • 3D-molded ankle straps for a secure fit with no pressure points
  • Quick-adjust forward lean for tool-free tweaks on the fly
  • Universal disc is compatible with all binding mounting patterns and allows fine-tuned stance adjustments

Almost perfect, Buuuuuuuuuut......

  • Familiarity: I've put it through the wringer

So I have a the 2011-2012 pair of sl's... They feel good all around. The only problem,"which is a big one", is every time I land with any kind of real pressure, the back foot ankle strap slips to a point of dangerous towards injury. I thought the teeth might have been worn down, but looked fine visually. I replaced them anyway to no avail. So I let the strap out a little in case it wasn't set long enough for my foot. No help... They just slip out all the time. Actually, I can't even tighten them down enough from the start. Which is a disappointing way to start each run. Seems like they could make a more solid ratcheting system for the price... Besides that, they seem like they would be perfect. Hope somebody from Union reads this.i gave it 2 stars to bring the overall rating down on the overview page.

Don't eat for a month and buy these instead

    This was my first time buying something online. I was worried about buying the right size binding, if they would show up where I ordered them to (aspen I'm from Toronto Canada ) and if the product was what it was cracked up to be.
    At no point I was I disappointed by the crew at dog funk. I was pointed in the right direction to the union SL

    From there the service was seamless and friendly. Moreover the bindings were sick. Super light (SL) as promised and filthy responsive. Combined with the attack banana this thing was carving before I could think about it.


    • Familiarity: I returned this product before using it

    Soft bindings, the technology has been proven because the components are the same as Drake used 10+ yrs ago. You are simply paying for the name, pure and simple. Nothing fancy.

    Regret buying them again as I have now moved on after a single use.

    I recommend looking for a better value and better built binding

    Pretty good could be better

    • Familiarity: I've put it through the wringer

    So far I like them still getting adjusted, I think these bindings could lose about 6 parts and cut some weight and still be the same but I'm not the engineer. I hate the toe straps and buckles, I can't get them to release easily and the straps sit up weird they don't really wrap the toe. I added my burton toestraps so these they work better now. the high back is lil soft but I like that, I had some carbon fiber highbacks and they were way too hard. I give these bindings a 6/10 rating

    cosmetic issues before being used

      I didn't use the bindings yet, so I will keep the review updated. But even before being installed on the board they have already two cosmetic issues - the paint which partial got off just being in the box, and the union onlay which just fell off....

      Hope that the riding quality will not be similar to this.

        Great bindings. Highback is crazy responsive, but tweakable enough side to side for good looking grabs. Nice and damp feeling for flat landings
        They are also indestructable; my roommate forgot to close the roof racks and the board flew off and slid on the bindings going 45mph. A bit scratched up but overall nothing wrong.
