If you’ve read my review of the Union Force men’s binding, then you’ll know I already love the binding for its versatility and reliability for all-mountain riding. Now, something you may not know is that if you have a boot size under a men’s size 10, then you would also be able to fit in the women’s version of the Union Force binding, the Union Trilogy binding.
Here is a review and comparison of the Women’s Union Trilogy Bindings to the Men’s Union Force Bindings. I own both of these bindings as part of my personal quiver and have been shuffling between both all season.
And, yes, I know these are women’s bindings. I am happy to rock them, though. I’ll cover the reasons why you might want to, too, depending on your size and budget.
Women’s Union Trilogy vs Men’s Union Force Binding Comparison
These bindings look nearly identical. Are they different in any way? Let’s find out.
The Feel of the Trilogy: Does it Feel Different From the Union Force?
The honest take is not really. It’s a hair lighter, so that makes the binding feel a little more agile, but otherwise the feel of these bindings is basically the same. They’re both outstanding resort bindings that are ready for anything.
A Note On Sizing: There is No XL Women’s Trilogy
There’s just one quick note on sizing you’ll want to know. There is no Trilogy binding currently offered for Women with a size larger than a US Women’s 11.0 or a Men’s 10.0. The sizes of the Trilogy are in Women’s sizes, too. So if you have a men’s 8-10 size boot, in the Men’s Forces you would have ridden a size medium, but in the Women’s Trilogy you would be in a size Large. This is due to the conversion between Men’s and Women’s Sizes.
Here are the size charts for both bindings to see how the Force and Trilogy sizes line up.
| Union Trilogy Sizes (Women’s Binding) | SMALL | MEDIUM | LARGE |
|---|---|---|---|
| US Men | * – 5.5 | 5.5 – 7.5 | 8 – 10 |
| US Women | 4 – 6.5 | 6.5 – 8.5 | 9 – 11 |
| Union ForceSizes (Men’s Binding) | X-SMALL | SMALL | MEDIUM | LARGE | X-LARGE |
|---|---|---|---|---|---|
| US Men | * – 5.5 | 5.5 – 7.5 | 8 – 10 | 10.5 – 13 | 13 – 15 |
| US Women | 4 – 6.5 | 6.5 – 8.5 | 9 – 11 | – | – |
So, Why Would Someone Choose the Union Trilogy Over the Union Force?
These bindings look the same, and they have a very similar feel. However, there are actually a few important distinctions that might push you one way or the other.
Sale Price / They’re Often Cheaper
You can find the Women’s Union Trilogy cheaper on sale than you can find the Men’s Union Force. I found mine on sale for $50 cheaper than the men’s Force.
Trilogy Binding’s Lower Highback Gives It a More Freestyle Feel
The Highback of the Women’s Trilogy Binding sits half an inch (.5 inches) lower on your boot than the Men’s Force. I measured the women’s Trilogy size Large highback at 7.75 inches high and a men’s Force size Medium Union Force at 8.25 inches high.
This is designed to offer more leverage and response for shorter riders. However, it’s also outstanding for the freestyle rider. The shorter highback in the Trilogy has a slightly softer flex than the Union Force, so the Trilogy offers a slightly more forgiving feel from side to side. This makes it easier to tweak grabs, press into rails, and shift your weight whenever you need to.
Different Color Options Between Force & Trilogy Bindings
The Trilogy is offered in a few different colors from the Union Force Bindings. But after that, the only other visual difference is the Union Font written on the heelcup and the model name written on the baseplate.
The Trilogy Bindings are Lighter
Union Force Medium (Equivalent to Women’s Large) Weighs 2.264 Per Binding
The Women’s Trilogy is 11.8grams lighter per binding than the Men’s Union Force. So it would reduce the weight of your setup by 23.6grams.
That’s not too much. It’s about the weight of one AA battery. It’s not nothing, though. Any weight reduction can help reduce some leg fatigue through the day.
It is such a slight difference, but here is how the weights compare.
- Union Force (M): 2.264 lbs per binding
- Union Trilogy (L): 2.238 lbs per binding (The large is equivalent to the Men’s medium size.)
- The Difference is the Trilogy is 0.026 lbs (11.8 grams) lighter per binding than the Union Force.
- Total Savings for the Pair: 0.052 lbs (approx. 23.6 grams).
- The Difference is the Trilogy is 0.026 lbs (11.8 grams) lighter per binding than the Union Force.
After that, these bindings are identical to each other. The baseplates and all other measurements, hardware, and technical specs are identical.

Verdict: The Trilogy is a Short Rider’s Secret Resort-Ready Binding
I’ll be honest with you. I was drawn to these bindings because I already loved my Union Forces. I bought the Union Trilogy bindings because they were cheaper (by $50 because they were on sale), and I was curious to see how a binding designed for a shorter rider (I am only 5’6″) would improve my riding.
While the performance differences between the Force and the Trilogy are subtle, it turns out there is a performance benefit to choosing the Trilogy over the Force if you are a shorter rider. With that being said, you could easily get used to either of these bindings without knowing what you’re missing in the other.
Overall, the Union Trilogy impressed me, and even though I originally bought them as a backup to my Union Forces, I wound up riding the Trilogy bindings more than my Forces this season.
Why is that? Well, because I lean more freestyle in my riding, the Trilogy bindings are ever so slightly softer and a little bit lighter than my Forces while still being equally as versatile to ride all over the resort. After that, the shorter highback matches my height a bit better, so I was getting less pain in my calves after a full day of riding.
I never realized how much highback geometry and sizing would impact my riding, but it did.
Stuck Deciding Between the Trilogy or Force?
So if you’re stuck deciding between the Force or Union Trilogy, I’d steer you like this. If you are 5’9″ or shorter with a boot size smaller than a men’s 10 (or women’s 11), take a look at the Trilogy over the Force. You’ll likely get them cheaper and have a binding that matches your height a little better.
Pros of Union Trilogy
- The new Union Trilogy bindings are versatile and perform well for most types of riding.
- The Trilogy offers a smooth riding feel with a strong level of response to help link your turns.
- The Trilogy’s new Molecular Bushing System offers extra dampening and shock absorption.
- The Union Trilogy offers great value for their price, and you can usually find the Women’s Union Trilogy cheaper than the Men’s Union Force.
- The Trilogy bindings offer so many customizations and tool-less adjustments.
- Union’s lifetime warranty guarantee on the baseplates and heelcups.
Cons of Union Trilogy
- There are cheaper similar options available like the Union Trilogy Classic Bindings (or Union Force Classic Bindings).
- The new Union Trilogy bindings will be too stiff for riders who enjoy soft flexing gear.
- Some riders find the Union Trilogy to feel heavy. They weigh 2.238lbs per binding with their hardware, so they add 4.476 in total to your setup.
