Light, quick, and precise, the Kastle FX86 skis are a fantastic choice for all-mountain skiing with a front side flair. Built with Kastle’s legendary quality, the FX86 has a lot going for it, and is able to provide strong skiing capabilities for advanced skiers who are really testing their limits and looking to improve. Built with a core consisting of numerous layers and stringers, these skis are a marvel of modern ski building technology. The central portion of the ski consists of vertically laminated stringers from beech and poplar wood. This is a dense blend of wood and gives the ski a solid backbone. Adding to that is a fiberglass wrap, and when glass is used in this manner, it gets a lot stiffer and more responsive. The additional vertical portions of the fiberglass act as another stringer that gives the ski its snap. On the outer portions of the ski’s core are a few more stringers of poplar and paulownia. These are lighter and more flexible wood structures that allow the ski to bend and play at the skier’s whim. It’s an all-encompassing build that a ton of skiers will love. Whether you want to take these skis into the bumps, trees, or keep them on the groomers, they’ll do everything that’s asked of them, and they’ll do it with more grace and style than anything else out there. At 86 mm underfoot, the Kastle FX86 skis are lightning-quick and can get from edge to edge with no trouble whatsoever.
