2025 Kastle ZX108

Freeride fun has never been so floaty and drifty. It’s been this way for a few years, but the new graphic spins this ski. When it first came out, the ZX 108 was made to bridge generations and usher in a new set of Kastle skiers. They put them at a lower price point to attract a new customer, and while the construction is a bit less sophisticated than some of the other model lines, it’s still very high end and high performance. The amazing part about the ZX 108 is that it’s such a fun-loving and drifty ski, but also still has a great sense of energy to it. For being that more mid-level of build, there’s a lot of pop built in. The things that we’ve loved about the ski carry forward to 2025, and hopefully this will attract a new group of skiers to the mix. It hasn’t been a particularly brisk seller for us at SkiEssentials, but we don’t think that’s representative of how they perform and the overall quality.

While slightly less sophisticated than some other Kastle models, ZX 108 still brings the tech. With a blend of poplar and beech in the wood core, the ski has a good mix of power and pop to propel skiers down the mountain. As opposed to the Paragon or MX lines, ZX uses wider stringers in more of a macroblock format. This is one of the main differences in terms of quality and precision. The more the stringers, the stiffer the ski will likely be, and a big part of that is the amount of epoxy used. With ZX, the wider strips of wood require less milling and less pressing—two things that can cost more time and money when building skis. On top and bottom of the wood core, we get two fiberglass laminates that create more energy and snap to the mix. Like all Kastle’s skis, we still get their Hollowtech vibration damping technology, and this works by reducing mass in the shovel to keep the unwanted chatter to a minimum. In the 184, we’re seeing a weight of 2160 grams per ski, so while it’s not a particularly light ski, it’s got the shape to make it more agile and maneuverable. This goes a long way in softer snow.

The shape is ideally suited to fresh and deep snow and fun-loving terrain. At 108 mm underfoot, this ski is right in the sweet spot for being able to float through endlessly deep snow as well as being agile enough for shorter and quicker turns in more technical terrain. The tip rocker is a lot longer than the tail rocker, making this more of a directional shape and style of a ski than something with more splay or a ski that’s more twin tipped. The lightness of the Hollowtech pairs well with the rocker and taper, as this ski simply stays on top of the snow and surfs right along with minimal hooking or catching. The tail is more business-like, with less relative taper and rocker. This allows the ski to cut through cleanly and more directly than something with more rocker. The ski boasts a turn radius of 19.2-meters, so while it’s capable of longer arcs, it’s also got a lighter swing weight in the shovel to make it appropriate for tighter turns and skids. The current style of straight/slash/straight/slash is very much in play here, as this ski falls more to the drifty side of the spectrum in terms of flex. This is truly a modern freeride shape.

ZX has an interesting demographic. We’ve loved this shape and overall concept for a few years now, and those emotions do not wane for 2025. We’re hopeful for these skis and their ability to handle soft snow, crud, and chop in a variety of formats. By opening the ZX line to a new generation of skiers, Kastle is hoping to reel in a younger group with this gateway ski. The appeal is to the youth, but that doesn’t mean aging and more reserved skiers won’t enjoy this ski as well. We all like to think that we’re young, but each year it just gets one step further away. Either way, the ZX 108 exudes youthful exuberance.
