G3 Ion 10 Binding

Why We Like The Ion 10 Binding

It only takes one steep skinner to learn the value of lightweight backcountry ski gear, but you also don't want to sacrifice downhill performance for an easier uphill. The G3 Ion 10 Binding is one of the few alpine touring bindings that weighs around a pound and still provides DIN settings suitable for rowdy-but-safe ski sessions in the backcountry. With lower release values than the Ion 12, this 4-10 version 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, helping to more effectively transfer power to the edges of wide freeride skis. The heel piece delivers better downhill performance and gives the heel the ability to absorb energy and maintain consistent forward pressure. Since touring bindings 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.

Perfect (when they don't jam)

I've put it through the wringer
135 lbs

I've now got 2 pairs of these on different skis and have been using them for 4 seasons in the backcountry. They are rock solid and give me great confidence on the up and the down. The ski crampon integration is really smooth as well, better than other brands I've seen. The only issue that I've come across, and unfortunately it's not too uncommon, is that the heel towers get frozen into the hiking position when ascending and it's extremely hard to get them to turn back into downhill mode. I always wear as thick of a glove as possible when cranking them over as once the ice/snow gives way they really snap back around and can be painful on frozen hands. All in all, would definitely buy again, just know this can happen.

Easily broken and not great service

I've used it several times

I know these have a lot of good reviews so I may be just an anomaly. However, I’ve used these a total of less than 20 times, and they’ve now broken for the second time. The first time when my brakes broke off from a minor fall, customer service took so long to get back to me about my claim (over 4 months of radio silence despite regular emails checking in on status) that I had already bought a replacement part before they sent me a new one. I’m not reckless with my gear, and I’m not even sure how the toe piece got bent backward this time, but I do know that I won’t be waiting on customer service this time around. Giving 2 stars because while they have worked they have been good bindings. Just a little fed up with buying replacement parts.

Great Binding!

I've used it several times

I was in the market looking for a touring binding and got a bit over-whelmed. After doing my research, I landed on the G3 based on the downhill ride aspect you get from this binding and not from a typical tech binding. While I enjoy the uphill, I am not looking for the lightest tech'iest binding, I am looking for a touring binding that will ride strong on the downhill. This one fits the bill. The whole technology system is super intuitive and works great when you are out in the field. I typically ride an 8 din, so the G3 10 was exactly what I was looking for. They also have a 12 if you ride a higher release rating and want to go for that. Got these with the Black Diamond Route Skis, and I am super pumped on my set-up!


What's new with ION for the 17/18 season

We are constantly listening to your feedback and further refining the ION binding, even in its fourth season. We gave the ION three important updates for 2017/18 to make it simpler, easier and more reliable. We made the BootStop simpler and lighter with no moving parts. We significantly beefed up the brake spring without adding weight. And most importantly we've redesigned the heel with an Auto-Rotation Lock that completely eliminates the chance of your heel rotating from tour mode to ski mode unintentionally.

Best Bindings!

I've put it through the wringer

I love these bindings. They are easy to get in and out of, and they are super lightweight. I use them in the resort sometimes and they feel solid. I will be using these for a long time!

Love and Security

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!

Great Tech Binding

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

Loving it!

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

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).
