G3 Ion LT 12 Review

The G3 Ion LT is a carefully engineered and designed, solid-functioning, all-around backcountry ski binding. The lack of a ski brake somewhat limits its appeal, but we'd argue that expert backcountry skiers (as opposed to "expert" resort skiers) don't need ski brakes.

Performance Comparison

We do wish the Ion LT were actually lighter. For this set of features and performance, there are options on the market that are many ounces lighter.

Touring Performance

The friction-less pivot and three levels of heel elevation put the Ion LT right in the mix with the best of the best in this category. Beginner skinners really appreciate the option to lift their heel to one of the three different levels. For 2019, most of our tested bindings include three lift levels.

The toe piece of the G3 is simultaneously minimalist and confidence inspiring.

Downhill Performance

Downhill performance is a wide-reaching category. We look at two major categories of information in this scoring metric. First, we consider how the bindings perform in normal skiing. How well is your boot held and what is the binding geometry as it pertains to downhill performance. We experienced no "pre-release" of these G3 bindings. This is good. The design includes a little bit of "forward pressure" at the heel that, at least theoretically, allows for greater binding elasticity in high energy downhill skiing. The stack height and heel-toe delta (difference in height) are almost exactly average.

Next, we consider what happens in non-standard downhill skiing situations. Essentially, how reliably and adjustably does the binding release and is the ski braked when it comes off. The bindings have a non-certified "release value" adjustment and no ski brakes. In these ways, the G3 Ion LT is relatively non-sophisticated.

Ease of Use

We can rate the ease of use of the Ion LT very highly. The toe piece is optimized for easy entry, and the heel lifters flip around very readily when you want to change them. In most ways, the simple yet carefully designed Ion LT is the top-scoring in terms of ease of use.

G3's flip heel lifters are widely loved. Indeed, it is nice to be able to use them from either side and to be able to move them with your pole basket.

Weight

The Ion LT is among the heaviest of the non-TUV certified bindings. This greater weight, as compared to something like most of our award winners, is attributable to greater usability features and the downhill "forward pressure" attribute. These things could very well justify the extra weight for you. Our test team definitely prefers lighter bindings, even if it means a little compromise in performance.

Durability

We had no problems at all with the durability or function of the Ion LT. Other users have briefly mentioned issues with the toe piece getting stuck in the locked position, but our extensive testing revealed no such problem. As initially compared to the construction of otherwise similar all metal bindings, the inclusion of plastic in the Ion LT is a little unnerving. However, the plastic is clearly carefully chosen and well-engineered. We experienced no breakage.

Value

These bindings are widely available, reasonably priced, and are backed up by a customer service system we have had good experiences with. There are better values out there, but not by much. If you find any sort of sale on the G3 Ion LT, that purchase will definitely rival even the value of our Best Buy award winner.

Transitioning from tour to ski on the G3 Ion LT can be done with the ski on your foot or off. Your personal style will inform.
