Light as a feather.

As one of the lightest female bindings on the market, the Union Women's Trilogy Snowboard Binding won't hold you back when you're sending the biggest jumps in the park, carving steep runs at high speeds, and surf-slashing through deep powder. Despite its incredibly lightweight feel, the Trilogy is pretty-near bombproof with its Duraflex ST baseplate. Union specifically developed Duraflex ST for cold-weather use, ensuring the binding's longevity for seasons to come, as backed by Union's lifetime warranty against breakage.

Armed with a Force Lady highback, the Trilogy seamlessly transitions from pow laps to park jumps without missing a beat, thanks to its ideal blend of responsive heelside support and lateral mobility for tweaking out grabs. The super-plush ankle strap features a 3D-formed design that comfortably wraps around your boot without painful pressure points. New for this year, the UltraGrip toe strap conforms to the shape of any boot with its anti-slip thermoplastic. This super-grippy material not only alleviates the slippage of previous toe strap designs, but it also provides multi-position versatility for a customizable feel. Choose to wear it over-the-front for a super-snug fit or rock it over-the-top for a more traditional feel.

All of the Things

  • Familiarity: I've put it through the wringer

Adjustability, Comfort, Quality... these bindings are awesome. I originally purchased these after I busted the heel cup on another pair of bindings. The Trilogy bindings have a quality build overall and offer an aluminium heel cup instead of plastic. The adjustability is great as well - you can tune these in for your own personal best fit. Overall, these bindings are durable, lightweight, comfortable, responsive -- what else could you ask for? I wear a size 8 in boots and the medium great.

Terrible sizing

    I wear a women's size 5 in the Nike Zoom Force so naturally I ordered these in bindings in a small. They arrived and although my size was within the chart for a small, these bindings were TOO SMALL. I paid for return shipping, asked backcountry if they knew if a medium would be too big and they just told me "if a small is too small, you need a medium" (aka not helpful at all). I then contacted Union for the dimensions of the mediums and they ASSURED me that the medium would fit as long as I put them on the smallest size. Guess what? The medium is too big in every way, the straps as small as they go, as tight as they go and still move. The binding is over an inch longer than my boot. So disappointed that their size chart has overlap between the small and medium and neither fit at all. Also terribly disappointed in the fact that backcountry was unable to offer any worthwhile help and that I have to pay for 2 return shippings.

    Big Step Up

      I ordered my sister a pair of the Trilogy's for a step up in her binding game. She had been using cheaper/ rental type bindings for the past year and her riding got to a point where she needed a step up.

      We paired her medium soft Salomon board with the medium flex Union Trilogy to create a great all mountain setup. The bindings are sweet and have a rock solid construction. She recently rocked the bindings on a 4 day powder bender and was crushing it.

      No negativity from this side of the powder aisle. Getting deep at the 'Tude

      Big Step Up

      Union, yes please

      • Familiarity: I've put it through the wringer

      I have been riding Union bindings for about 4 or so years now. Absolutely love Union. These bindings are super light. I have them on my Never Summer Onyx board and I have actually rode them on my Clovis powder board before. So with that being said you can ride them all over the mountain on any type of snow. They are really responsive and an extremely durable binding. Probably my favorite bindings I have rode. The toe strap is great since it goes directly over your toes.

      I wear a size 6 boot and ordered the size small binding. Size is great.

      If you have gear questions feel free to reach out to me directly.

      she loves them!

      • Familiarity: I gave it as a gift but have feedback to share

      I gave these to my cousin as a Christmas present and she loves them. She is getting better and better at snowboarding and need to upgrade her bindings on her current board. These bindings were softer than she expected but that makes sense because they are not supposed to be stiff bindings, as they are right in the middle on the stiffness scale. She doesn't ride much park yet but she might start and this is a good binding for that. She does more all mountain riding and this is the perfect binding for her.

      How did I survive without these?

      • Familiarity: I've used it several times

      After 7 years, I needed to upgrade my bindings. It's hard to look at how binding technology has progressed and think that they can't make a huge difference in riding: most have two straps and a support backing. How different can bindings actually be? ... These are a game-changer for me. I've used the product in several scenarios: groomers, bumps, off-piste and wide open powdery side/backcountry and am thrilled with how much more effortless and fun riding has become.
      As many reviewers have stated, the weight and the responsiveness exceeds expectations - I agree. One of my favorite parts of the bindings is the webbing on the toe strap - it's really flexible (almost rubbery) and allows for a really snug fit around the toes without having to tighten to the point of numbness. The subtle hits of rose gold add a hit of style that I also like. All round, I can't wait to ride these more. Would recommend to anyone (regardless of riding style).

      Light weight but built strong!

      • Familiarity: I've used it several times

      I absolutely love the Union Trilogy bindings! I've been riding with them for about a month now and could not be happier! They are light weight but built super strong! Strapping into these bindings is super smooth and easy! The ankle straps are very comfortable and, true to the description, doesn’t give me painful pressure points like other bindings sometimes do. I love how the toe strap forms to the toe of my boot perfectly and does not slip off. Union made it super easy to adjust the straps on the fly, if needed. I’ve ridden in all kinds of weather conditions with these bindings and they have not let me down. They’re built really well, so I know they will last for many future winter seasons!

      For Chicks Who Rip

      • Familiarity: I gave it as a gift but have feedback to share

      The Trilogy by Union is essentially the womens version of the Force, one of Unions top selling and best bindings out for over a decade now. This is an aggressive binding that is definitely made to drive progression in ones riding while still remaining light enough to toss around in the park or backcountry alike! Great binding from one of the best binding companies around. Made for ripping!


      • Familiarity: I gave it as a gift but have feedback to share

      I got these for someone as a gift. They are beautiful, and super are the bindings! She has used them all around the mountain and has no complaints. They are solid, light, and durable, 10 out of 10 would buy again.

      Very light weight and so pretty

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

      I bought these bindings for my never summer infinity 2017 very lately. They are super light-weighted and the metal part of the clip is rose gold plated, so pretty! Love them so far!

      The Ladies' quiver killer

      • Familiarity: I've put it through the wringer

      I can't say I've ridden these bindings, but I own the Union Forces and they are the same binding in the Men's version.

      These are my favorite all time binding design that I've ever owned. They are extremely durable, lightweight, and the perfect flex for any style of riding. The multi-zone highback is the kicker; stiffer at the bottom for response when you need it, and progressively softer as you near the top for tweaking out your grabs or going through the park. I can't say enough. I love these things and you will too.

      Don't believe me? Transworld Magazine selected them as the "Top Women's Freestyle Binding" pick for the last few years.

      Oh the ankle strap, though!

      • Familiarity: I've put it through the wringer

      This is a super lightweight binding and I've loved the responsive nice I get on it.

      My favorite part of this binding is the ankle strap. I definitely prefer the ankle strap on these to my Burton binding I have as my backup pair. It's totally comfortable and love that the updated version has taken some extra material out of the toe strap! Love these bindings and definitely want to step in an updated pair.

      True to size, I wear a size 7 boot, and am in a M binding.

      All Arounder

        Looking for a binding to ride it all? Groomers, powder, jumps, rails, high speed, low speed, comfort, performance, lightweight, strength, and long lasting are a few things the Union Trilogy does and is. The Trilogy really is hard to beat no matter how you look at it, which is why so many riders pick it as their go-to binding. This year the rose gold accents give it a stunning appearance to go along with its ripping performance. You will not be disappointed with the Union Trilogy no matter your ability level.

        feather weight

        • Familiarity: I've put it through the wringer

        Not Only is the Union Trilogy one of the lightest bindings in the women's market coming in at 650 grams but it is arguably one of the most comfortable bindings at this price as well. Backed by riders like Jess Kimura and Jamie Anderson this binding is undeniably one of the toughest best performance bindings for its class. With the Force lady high back you get a multi zone flex so you can tweak those sick grabs but also get the support and performance to keep up with the boys in the steep terrain. The sonic fused lady ankle strap is very comfortable and durable for any style of lady rider and with the new ultra grip toe strap your heel will be pushed all the way back in the Extruded aluminum heel loop. The magnesium ratchets also help because they won't freeze or lock to help with easy entry and exit. Whether your looking to ride a steep powder face or get gnarly in the park this binding will take whatever you throw at it.
