2025 Kastle Paragon 107

The 2025 Kastle Paragon 107 is an absolute rocket ship of a ski. As the widest of the new Paragon line, it’s the floatiest, obviously, but it’s also the hardest charging. Versus the totally capable 101, the 107 is just more stable, stouter, and more amenable to higher speeds and longer turns. You could argue that the skis have a limit in the shorter turning and slower speed zones, but that’s not what they’re built or designed for. As the de facto replacement for the FX 106, the new Paragon 107 features a sturdy build like the FX, but a more freeride-oriented shape like the ZX 108. This mixing of attributes pays dividends out there on the hill, mixing stability and power with flotation and versatility. At the end of the day, this ski is happier at speed and driven rather aggressively. When done properly, skilled skiers can unlock the playfulness and creativity.

We get an all-new build with this new Paragon 107. Kastle uses their InfiniCore construction to mix different levels and layers of beech, poplar, and paulownia wood to create the desired effect. The dense beech stringers are found mostly underfoot and through the mid-section of the ski while the lighter poplar and paulownia takes up more space along the sides. This allows the engineers limitless creativity when designing the flex and performance of the ski. In addition, we get two full sheets of metal that stop just before the hollowtech tips. This makes the fronts of the ski lighter and more amenable to quicker turns and increased agility. In the 184, the ski weighs just over 2kg at 2053 grams per ski. This is sturdy enough to keep it on track at high speeds while remaining agile enough for mobile zones and creative skiing. Tester Chris Moykens states that he was “impressed by the overall versatility of the Paragon 107. It felt light and lively in the powder and solid under foot on the packed/chopped snow in the middle of the trails. It performed more that adequately on everything I took it on.”

By sharing a mold with the ZX 108, they’rer not only able to keep costs slightly lower, but also to cash in on a fun and freeridey shape. The Paragon 107 has longer tip rocker, shorter tail rocker, increased tip taper, and a relatively flat tail. The tail is where we see the main difference between ZX, as the Paragon 107 has slightly higher tail rocker. This makes sense when considering the stiffer flex and stronger build. The 184 produces a 19.2-meter turn radius which is great for mixing high speed carves with crud busting capabilities. Chris goes on to state that “This ski is billed as Kastle's new all-mountain/freeride ski so it's no surprise that it performed well on the front-side of the mountain as well as in the slack-country. This ski is most at home in fresh, soft snow.” While that’s certainly true, another tester, Zach Arvin, states that he’s “curious to see how it would perform on groomers but based on what I skied, it would perform very highly.”

The 107 feels more like the expert option in the Paragon line, and that’s no mistake. When you’re looking to take your skills to the next level and push some boundaries, you’ll need a ski like this on your feet. Paragon has a lot of upside here for fans of going fast and charging hard. We’re not sure there’s a lot of intermediate skiers who will have much success here—better stay in the ZX range or look narrower in Paragon.
