Few riders can truly "do it all" the way Torstein Horgmo does. From winning park contests and crushing rails in the streets to going huge in the backcountry, Torstein gets it done with the help of the Union Factory Snowboard Binding.

The extruded anodized aluminum heelcup reduces weight while maintaining strength and stiffness, and it never loses it's shape no matter how much you abuse it. The Stage III Atlas baseplate makes minimal contact with your board to eliminate dead zones in the board's flex beneath your feet. It also has a Team highback to make it flexible enough to tweak grabs, yet stiff enough for reliable response and support, and injected EVA bushings dampen vibrations for a smooth ride.

Canted Gas Pedals align your legs more naturally to reduce fatigue, and they improve leverage for more ollie power for riders with wider stances. The SonicFused ankle strap minimizes stitching to increase overall durability, 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. Plus, magnesium buckles shave even more weight while increasing strength.

  • Team highback
  • Stage III Atlas Duraflex baseplate
  • Extruded aluminum heelcup
  • Multizone EVA footbed with Canted Gas Pedals
  • 3D Direct Connect ankle strap
  • Ultra Grip toe strap
  • Grade 8.8 steel hardware

Check your size twice

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

Seems like a pretty good gear, but my boots don't fit. I can't use it and can't return it, it's too complicated because of my location. I have Salomon Synapse boots, size 9.5 US and bought M/L bindings. Overall it fits, base plate width and length is good, toe strap can be adjusted. But ankle strap is way too short, even adjusted for maximum length it shifts horizontally and can't be centered properly on my ankle. Feels wrong and uncomfortable. So keep in mind that Salomon boots have bigger outer size relative to boots of other manufacturers in same sizes. I still think that most other boots in 9.5 US will fit, but be careful if you wear Salomon.




    I have K2 boots size:10.5 us
    Are the M/L size too small ?


    Realistically the 10.5's will be a hair too big for the M/L's. Sorry for the bummer news.

    Shoot me an email anytime you have questions!

    All day comfort

    Having bought the k2 maysis in a size 10 (US) what size union factory binding should I hit up as this size falls slap in the middle of the M/L and L/XL??

    Best Answer


    My personal preference is to go with the smallest binding that will fit my boot. It looks like size 10 boots are the large end of the M/L, which is what I would go with. That way you have better response and dont run the risk of the baseplate of the binding being too large for your board.


    Great bindings

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

    Love the bindings. Took em out for the first time on a new powder set up. Had really quick heel/toe response in the trees, tons of padding for drops. Only thing I didn't like is that the screws connecting the plate to the board got loose a couple times. Not a big deal, kind of expected it with a new setup. But the padding on the footplate covers the screws, so you have to take the padding out in order to tighten em up again. Little annoying, but still great bindings.

    I saw comments on another site that the base of this binding is very long, and in some cases overhung standard sized boards. Can someone please provide the length of the L/XL size of this binding?

    Best Answer

    David R,

    The length of the footprint of the L./XL size measures 26 cm (260mm) from end to end.

    Thanks much Grant, these will just barley fit by board OK. Now if the price would drop a little more....


    Great binding in all aspects

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

    Just bought these after my Burton Missions BROKE in half on me. I wanted/needed something more durable and heavy duty. These are the perfect mix of strength, weight and flexibility. I love more flexible bindings that can handle cliff drops, a little bit of park, and shredding the groomers.

    I took them out to Vail last weekend on a nice powder day and they performed amazingly. Would highly recommend these bindings.

    Great binding in all aspects

    Good, but not Great

      Bought these, but had some serious issues with getting locked in. Had to make adjustments all the way down the mountain. They're super indestructible and have shock absorbtion like no other, but they only make two sizes. I tried them out for am


      Riding perfection

      I have last year's model, which are hardly any different from the new model. Solid, comfy, light, responsive, and highly recommended.


      All rounder'

      • Familiarity:I've used it several times

      So far so good with this binding. I've ridden it since the start of this season and it's holding up well.

      These bindings felt weird at first since I came from an old school ( early 04' ride binding) that was pretty stiff.

      These bindings are stiff in the ways you want and loose in the ways you love. Heel to toe response is quick but as soon as you tweak or start surfing through some berms, it all starts to make sense.

      I wear a 8.5 Burton Ruler boot, Size M/L is what I chose.

      Hi Kyle,
      Will these bindings connect with Jones Hovercraft board?

      Thank you Kyle!
      I have 10.5 size boots and want to by ML size of the bindings. I heard that XL are too big. What do you think?

      I think you could get away with the medium large. You're really in between sizes there, so if you get them, before you mount them or anything, pull the binding out and put a boot in it.

      then adjust the latches. ( all are adjustable) and see how far it clicks down and if it creates any weird pressure spots.


      The Ultimate

      • Familiarity:I've put it through the wringer

      I Love this binding. It has a nice sturdy base which still gives a little side to side roll, but the toe to heel response is killer. Super comfy top of the line straps, canting in the base to help the knees feel good after long days on hill and the highback is a great blend of response and flex.
