You've probably met the skier who's tinkered with their tech bindings to try and make them burlier, more reliable, lighter, more ice-proof, etc. Sometimes the mods have worked, but most of the time they haven't, but they are almost always convinced that they've revolutionized touring each time they emerge from the garage. Unfortunately for tinkerers everywhere, G3's ahead of the curve and is starting to change the game with the new Ion Tech Binding. It'd be hyperbolic to call it revolutionary, but the Ion introduces a whole host of killer features without compromising the classic two-pin toe and heel tech design that's worked so well for so long.

G3 started by giving the Ion an adjustable forward-pressure setting, which allows 22mm of adjustment to ensure a super-solid connection between the heel of your boot and the heel piece of the binding, reducing vibration and helping to eliminate chatter. This gives the Ion a smoother, less rattly feel than traditional tech setups and makes sure that it'll release consistently, but only when it's necessary (it's release values run as high as 12, if you're wondering). The mounting pattern is 33% wider than standard tech bindings, as are the toe jaws, making it easier to get power to the edges of wide skis and reducing vibration for a easier, more powerful ride in rugged conditions. G3 even built in a Boot Stop step-in guidance system, which employs two bumpers that let you settle your boot down in the right spot without trying and retract when you click into ski mode to stay out of the way.

The Ion crushes it on the way down, to be sure, but it'd be pretty worthless if it didn't go up like the dickens, too. Luckily it does, with thoughtful features like bi-directional heel rotation—no more forgetting which way is right and which left—and dual Quick-Flick heel lifts that are easy to manipulate with a ski pole. Maybe the best innovations are the toe piece's double snow-clearing channels under the jaws, which let you poke out snow with a ski pole, ensuring that you won't ever accidentally start to ski without the toe pins being fully engaged. The Ion also boasts a fully retracting alpine-style brake for solid and reliable ski-stopping performance for when you do eject.

The Tech Binding to get!

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

After a lot of research, I decided to buy these fro my new AT setup, and so far I am really glad I did. Very easy to use. Switching between modes and clicking into the binding is effortless. Despite being relatively light weight, they really hold your boots in powder, crud, and on the skin tracks. Do follow the instructions for clearing the snow piece and ice. As others have said, these are the new standard for Tech Bindings.

Best advice

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

I asked around and the G3 ION is what was recommended over and over. Simple and Sweet.

incredibly terrific binding

  • Familiarity: I've put it through the wringer

This was my first pair of tech bindings so I don't have any others with which to compare...and I never will. This binding has been absolutely bomber. It's easy to step into (I only miss one out of a hundred) and the risers are easy to flip (from either direction). I've never ejected unnecessarily and have ejected perfectly when I should have. As I said above, I'll never know what other bindings are like because I will only ever buy this binding again. I bought the 10s for my lighter wife and she loves them too.

Gave as gift

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

My friend is super happy with these bindings. They're light and easy to step into.
Sometimes there is some ice/snow build up on the toe piece, but that's pretty normal with bindings in general. They're easy to move in and out of ski/walk mode too.

Most excellent first winter

  • Familiarity: I've put it through the wringer

Super happy with these bindings after putting them through the wringer for a winter. I never thought the toe guides would be a big deal, but they have made stepping in infinitely easier than any bindings I've used in the past. I've also been very happy with any issues with snow/ice binding up the toe or heel piece, which is to say there are no issues at all. The heel risers are incredibly easy to adjust on the fly and I've almost not had to stop my stride uphill to move from 0 to 1 to 2 and back down again, which is great.
Also, though not its intended use, I rode these bindings a fair amount inbounds, mostly on s**tty concrete PNW crude. The bindings held nicely and never released inappropriately. Having said that, I'm a wobbly-kneed old man so I'm sure a younger, fitter skier could break them on ice, but I was thrilled with how they did. Five stars, would ride again....

Good Binding, Frustrating G3 Service

  • Familiarity: I've put it through the wringer

Ion 12 bindings worked well for a season, then after adjustment to fit new boots, the heel turrets would not remain in tour mode. Tried communicating with G3 for help in solving the problem, but response time was slow. Bindings eventually sent to G3. Bindings have been at G3 for > 2 months, with no meaningful information coming from them about findings, status, or plans to fix/replace/return. In the meantime, winter is slipping away. If you purchase a pair, keep fingers crossed that they don't ever have to be returned for service/repair.

Heel Screw problems

  • Familiarity: I've used it several times

The bindings themselves are great, minus the fact that they are being recalled by G3. There is another issue, which is the heel screws. The screws are larger than the toe unit screws and not tapered. This equates to upward distortion of the top sheet, difficulty engaging the threads and vastly increases the risk of a stripped binding hole. I have mounted many sets of bindings and never before had a binding screw hole stripped. This happened twice in two mounts despite approximately 100 pounds of down force to persuade the threads to engage and follow themselves. I am not sure what made G3 believe that they should have two different screw designs for one binding, and why they chose to deviate from the industry norm, but it was not well thought out.

Great Bindings!!!

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

I love these bindings. I haven't got to use them much this year because we are waiting on the snow. They have a solid and durable construction. They are easy to get in an out of.
I know its not important but I do love the color.
Highly recommend these bindings!!!

Skier friendly

  • Familiarity: I've put it through the wringer

First full season on g3's during 16/17 winter. Very easy to use and durable. Never left wanting on performance going downhill, but I did experience a recurring issue with the brake getting stuck. Snow tends to collect and ice up, tripping the brake when walking. It's not a huge issue, but it is annoying. Maybe it's user error?

Choosing the Best AT Binding

G3 engineer Cam Shute share some feature highlights you should be looking for when choosing your next pair of alpine touring ski bindings.

What's New for the '17-'18 Ion Binding

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.

excellent

  • Familiarity: I've put it through the wringer

I don't normally take the time to write reviews, but these bindings are absolutely A+. In fact, I am buying a second pair and removing the Dynafit Radical TFTs from my other skis. Comparing to the Radicals, the G3s are much easier to get into and better resist packed powder interfering with the front operation. Highly recommended.

First Impressions - Super Great

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

Took these out for their maiden voyage today, here are first impressions:

Easy to line up toe and step in. As others mentioned, they really click into place, too, and reinforce the fact that they have locked on.

LOVE the lack of ramp angle. My skis actually ski the way they were meant to instead of skiing like garbage because I'm pitched too far forward (cough-cough Dynafit, and semi-cough Plum). And they were plenty comfortable skiing on groomers. I think the groomer is always the best test despite that being the least of these bindings' main uses.

Easy to flip the heel risers, love the design there. I just wish the tallest riser was a bit taller. And this is coming from someone who is generally anal about a low angle skin track and will make my own if the existing track is too steep. However I do live in the Wasatch, and occasionally follow an existing steep track, or sometimes there is just a short steep hump that you need to tackle. So.... a higher 3rd position would be nice.

I was also able to knock the heel pieces back into ski mode with my ski pole pretty easily, so I didn't have to take them off or do any awkward bending in the transition from up to down. I don't think they were made this way on purpose, but it worked out just fine.

A Mixed Bag

  • Familiarity: I've put it through the wringer

I have mixed feelings about this binding. Things I like:
-- Easy step in. Those little plastic guides do make a difference when you're in a hurry.
-- Brakes worked great for me. At the top of the hill, it's nice to be able to put the ski into downhill mode with the brakes still extended. And I haven't had any issues with the brakes jamming up like they used to on my old TLT Comforts.
-- They look pretty snazzy.

Now my gripes:
-- You can't replace the brakes. I'm upgrading to a wider pair of skis, so I need a wider set of brakes. Easy enough, right? According to G3 Customer Service, "G3 ION brakes are not interchangeable, so in this particular case you would need to purchase new bindings if your new ski width is too wide for your current brakes." Seriously!? This is the first set of bindings where I've ever had with this issue. Looks like I'll need to scrap/sell the bindings after just a couple of years of use.
-- Occasional pre-release. Not too bad, but I've had occasional pre-releases when skiing on hard snow and hitting a bump or when skiing on soft snow and flexing the ski a lot. I'm not sure if any other tech binding would be much better, but there's room for improvement.

Best Tech binding on the market!

  • Familiarity: I've put it through the wringer

I've been on the ION 12 all winter and have been extremely impressed. The toe piece is bombproof and simple. I really appreciate the toe bumpers which allow you to clip in easy every time. Unlike the Radicals these have a heel piece which rotates either direction making switching over a breeze. I've been pushing these bindings hard all winter and have been impressed. Once clipped in, I feel solid, with no play. If you have any questions or would like to pick up a pair, please reach out.

Solid feel

  • Familiarity: I've used it several times

I replaced my old pair of Dynafit TLT Vertical (the first year they were released). So better performance on bindings should be expected at this point. These are great. I feel like there is a solid engagement and they ski well. I've used them both in bounds and touring and they have a very ensuring feel to them.

Only cumbersome issue is the need to remove skis to go from ski to tour mode and vice versa. You can get them into ski mode from tour mode without removing, but it's cumbersome and just seems easier to remove the ski.

Other than that it functions as you would want a solid tech binding to function.

Awesome bindings

  • Familiarity: I've put it through the wringer

I have been using the Ions for three winters for well over 100 days per winter and have been really happy with their performance. The toe piece never clogs with snow, an issue that happens frequency with Dynafit toe pieces. The springs on the toe also have a snappier action, giving you confidence when you step in that the binding is correctly attached to your boot. I store my skis outside all winter and have no issues with the brakes not locking into walk mode.

solid backcountry binding!

  • Familiarity: I've put it through the wringer

After skiing this as my only tech binding for 3 years (I'm a g3 athlete), I've only ever had issues with the brake icing a little and being stuck up after transitioning skin-ski.
Beyond that, I've found it effective for both releases when it should when I crash, and maybe 2 unwanted pre-releases over 200 days of skiing.
Beyond that, it's light, durable, and has a better heel riser design than other tech bindings I've used, which are difficult to flip.

Room for improvement

  • Familiarity: I've put it through the wringer

I have 20 or so days on this binding with a mixture of ski mountaineering, backcountry and resort use.

Construction seems solid, good ski crampon attachment and I can install crampons with the ski on if needed. Tours well on the flats. Good ski brakes.

Difficult to change to ski mode with the ski on compared to my Dynafits, and must remove ski to change back to tour mode. Highest climbing aid is not high enough for steeper ski tracks.

The heel rotates a bit on each turn on hard snow which makes the ski feel like it has a big base bevel. Same ski with alpine bindings skis with way more energy and rebound.

I have skied some really steep hard snow, no fall zones, ski resort bumps all with no pre-release, and at this point no hesitation to charge.

I'll be looking at the Fritschi with lateral toe release for the next setup.

UPDATE
I lost a ski crampon last week after the release cable apparently froze to the bottom of my boot, and when I lifted my heel, the crampon released and was last seen bouncing over a cliff. That could never happen with the Dynafit style crampon mount.
