The flagship for female freestyle.

Union finally gave in to the demands of hard-charging ladies who wanted a binding that combines the bomb-proof durability and lightweight feel of the best-selling Men's Force binding with a chic look that doesn't hide their feminine sensibilities. The result is the Union Women's Trilogy Snowboard Binding, an all-mountain destroyer that kicks ass, takes names, and looks good while doing it.

The Trilogy II baseplate may be the lightest on the market, but don't let that fool you into thinking it's just a delicate little flower—it's backed up with a lifetime warranty to show you it means business when it comes to durability. Get flex where you want it and support where you need it with the Multizone Trilogy highback. It's stiffer towards the bottom and more flexible at the top so you can tweak your tricks without sacrificing support.

It also has an extruded 3D aluminum heelcup to reduce weight while maintaining strength and stiffness. 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.

Pretty Good Stuff

  • Familiarity: I've put it through the wringer

Soooo I eat gear and these have gotten me through 1/2 a season so far with 60+ days on them so pretty solid bindings in my mind. Did break a ladder in -30 temps. Now carry back up parts for all my b/c adventures in case something goes, but so far so good (knock on wood). I will say the fit much smaller than the sizing chart. I ordered M/L originally as I wear a size 7 boot, but found even when adjusting to the smallest size it was way too big. Returned and went down to S/M and fits perfect. Still room to make bigger, its not maxed out on a 7. Seems tough for now. Doesn't stay pretty for long because of the matte finishing, but having pretty gear isn't my thing :) Also baseplate likes to ice up in super deep pow, nothing a friend with a ski pole can't chip away if needed. Over all really good stuff Union!

I wear a size 7 womens boot. Would those...

I wear a size 7 womens boot. Would those work in a S/M? I have looked at several sizing charts that are each a little diffrent.

Responded on

Hey Jessica,
Thanks for your question! According to the size of your boot, they will fit in a S/M size binding. You may want to adjust the ankle and toe straps so the straps fits over you boot comfortably. I have attached a "How to:" video that will help you adjust your binding to your boot.


Responded on

S/M for sure! I bought the M/L and they were WAY too big for a 7. Had to return. Just adjust everything as needed!

Tough and light

  • Familiarity: I've used it several times

Super light. It almost feels like there's nothing on your feet. These make the ride a lot more comfortable and responsive. The one thing I didn't like was the difficultly of the release. As I've used them more, they have loosened up a little, but still have difficulty occasionally.

Good stuff!

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

I've been skeptical about purchasing bindings that aren't Rides for a few years, but after doing my research I decided on these. Super pleased with my choice! These things are tough, and light at the same time. Getting them set up was a little different because you really have to thread the screws into the base plate, but other than that, I think it'll be a fun season!

Best all around Lady's Binder!!

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

I bought these as a gift for my lady & she absolutely Loves them!! I've been riding the Forces for years so when she needed a new pair I wasn't letting her ride anything else!! She loves the comfort & light weight of them most but keeps talking about how responsive they are when she needs to get after it! she's a sz 8, so I got her the M/L Trilogys in White to match her new Capita, Birds of a Feather board.

Excellent Bindings

  • Familiarity: I've put it through the wringer

These are probably the first female specific bindings that I have bought and I do love them. All the hardware and straps are still in tact after using these for two seasons now.

Much lighter binding than what I am used to and so far I am enjoying the binding.

  • Familiarity: I've put it through the wringer

These are by far the best bindings I've ever owned. They're strong and responsive. Made it 100+ days on the mountain with zero problems. I feel safe and comfortable in them. Mine have definitely taken a beating, but haven't slowed down one bit. Still as happy with them as I was on day 1.
I love Union Binding Company!!!
