Fiddle-free tech bindings.
Improving on the proven performance of tech bindings takes knowledge of what works and what doesn't. And while G3's Ion 10 Alpine Touring Binding might not be revolutionary in design, it does improve on the proven designs of tech bindings by refining some of the finer aspects of their design, resulting in a better skiing, more efficient, and hassle-free backcountry binding.
With lower release values than the Ion 12, this 4-10 version of the Ion is ideal for the lighter, less-aggressive skier who doesn't need the extra retention. The Ion 10 maintains the same freeride design of the 12 with a wide mount that's 33% wider than traditional tech bindings, giving the binding the ability to more effectively transfer power to the edges of wide, freeride skis. The heel piece delivers better downhill performance with forward pressure heel elasticity—this gives the heel the ability to absorb energy and maintain consistent forward pressure, resulting in more consistent release values and improved downhill performance. Since touring bindings will spend the majority of their time going up, G3 refined the climbing features on the Ion, so you'll spend less time trying to figure out which way to turn the heel piece, scraping ice from the toe piece, and trying to get your toe into the binding.
In addition to the wider design and increased elasticity in the toe piece, it is also equipped with a step-in guidance feature that puts your boot exactly where it needs to be for a quick and secure clamp. The heel piece can be turned in any direction, so you won't have to worry about turning it the wrong way, while the quickflick heel risers have an intuitive design, allowing them to be quickly grabbed by either a pole or hand. The toe piece has a snow clearing channel to keep the area beneath the toe springs free of ice and debris to ensure a solid and reliable attachment to the boot. Another nice feature on the Ion is the brake's ability to remain engaged until the boot actually disengages it, so you won't have to worry about losing a ski if the binding is in walk mode. All adjustments on the binding can be made with a #3 posi drive, so you can leave a few extra tools out of your pack.

- Q & A
Love and Security
- Familiarity: I've put it through the wringer
Love the G3 ion's. The moment you step in these you can feel the security over some of the other tech bindings in the industry. Toe piece is elevated to prevent that typical high heel/low toe feeling of tech bindings. I won't be switching to anything else anytime soon.
So far so good!
- Familiarity: I gave it as a gift but have feedback to share
Bought these as a gift for my sister. She is loving them. they have been working perfectly for her and she feels like they are going to last forever
Great Tech Binding
- Familiarity: I've used it several times
I own both these and the Dynafit ST Radical and would recommend these just because of the ease of entry. With the guides on the toe piece stepping into the binding is incredibly easy, especially in comparison to the radical. I think they both ski the exact same, both feel secure and lightweight. If I were to choose I would go with the ion to forego the frustration of getting into a tech binding in sketchy situations.
Great tour binding
I'm happy with my purchase of the G3 ion 10. I contemplated the Dynafits and even the Ion12 but decided on these because of simplicity of use and reviews. Backcountry tech chat was also super helpful. I really didn't need the extra din settings of the ion 12 and the functionality of both bindings were the same other wise. I'm purchasing powder skis and will order another set of these bindings
- Familiarity: I've used it once or twice and have initial impressions
One use so far and can already tell I am glad I went with these bindings. Lightweight, feels solid and very easy to switch from ski to tour mode. I had the 100mm mounted on Atomic Century skis with a 102 underfoot (the breaks flare and fit perfectly).
What is the hole pattern of the mounting screws? Any chance it is compatible with the older Dynafit models (5 screw toe, 4 screw heel)?
Are the brakes on this binding removable?
Hey Nolan - The brakes are not removable on the G3 ION Bindings. Feel free to contact me directly with any additional questions.
- Kyle L. - Expert Gearhead
Have a ski waist of 120, would it be better to go with a 115mm break and bend out to fit or just go with the bigger 130mm break?
Nick, I would go with the 115 mm brake and then bend it out. This way you dont have to worry about the brake docking in the snow should you achieve some really high edge angles on those new skis!
If you have anymore questions feel free to send me an email or call my direct line!
How do these compare DIN wise to regular freeride or framed AT bindings? I know there are differences, but is it so different that if I have my DIN set at 8 on my freeride skis, will I still be "about" an 8 with these?
If not, is 10 a high enough setting?
The release values do not correspond to DIN. They are specific to the G3 Ions and the bindings will come with a handbook including a release value chart; you can see it on the G3 website.
Do these have 22mm of elastic travel like the Ion 12s? Is the travel considered vertical, lateral or both?
How wide is the mounting pattern compared to the Dynafit Radical 2.0?
How does the elastic travel compare to the Dynafit Radical 2.0?
What is the heel hight, toe height, and drop for these bindings?
Do they have a rotating toe piece?
Robby, here is the info I got from G3 Direct and some research on Wildsnow.com:
Since Lou says it better than me, I will just quote him and add in some comments from G3
"Pintech” bindings ‘forward pressure’ systems do not provide release elasticity, meaning they’re not providing any sort of return-to-center help with vertical (upwards) release. Instead, they’re simply there to allow the ski to flex and make release values more consistent depending on ski flex." - Lou Dawson
G3 says this is true but, the forward pressure spring does absorb energy in the case of hard landings which prevents the boot from slamming into the heel unit in the event of a big compression. This also adds a layer of durability to the binding.
The heel unit slides fore/aft 6mm under spring load to compensate for ski flex - aka the forward pressure. The toe is a traditional tech toe that is stationary. So there is not any lateral or vertical travel in the toe piece.
The Dynafit Radical 2.0 has a 2mm or so wider mounting pattern than the Ion after measuring them.
Have not gotten a measurement from Dynafit on the elastic travel comparison, just shot them over an email. The Ion has 6mm of forward pressure where the Radical 2.0 is 10mm.
The Ion's toe height is 40 mm, the heel is 53 mm which is a difference of 13 mm versus the Radical 2.0.
Hope this helps, Ill see if I can get the exact same info from Dynafit as well.
These (and other G3 bindings) will fit fine with the new Atomic backland boots right? I know the Beast and Kingpin might not...
Andrew, the Backland boots will work with this binding no problem. I'd have to double check with Atomic but, I can imagine there might be some compatibility issues with the specialized tech bindings like the Beast and KingPin. The toe and heel welts are smaller and therefore like the Scarpa Alien dont fit in the King Pin or Beast, although that boot doesnt really fit in line with that binding anyway, the Backland is somewhat of a game changer.
Either way, the Backland and ION are a perfect match.
If you have anymore questions feel free to send me an email or call!
Found out the Backland does work with the Beast but, not with the King Pin.
