„I’m always attracted to steep, narrow couloirs and for this I need a faithful companion. I found it in the TX98. Its optimized weight does not require much more effort on the accent, but I get the unbeatable lift and stability on the descent, allowing me to easily forget any struggles on the climb."
David Lama
Innovative carbon construction with DUALRISE technology and HOLLOWTECH 2.0 ensures playful descents in powder. The TX98's unbeatable downhill performance is further optimized with its lightweight contruction. This ski is ideal for ambitious backcountry skiers focused on discovering untracked powder.

With proven technologies inspired by racing and utilizing only the finest raw materials, we create unique skis, made in Austria, for each category. Sophisticated Sandwich-Sidewall Constructions and patented technologies create new benchmarks in performance standards.


Our patented, key technology is unique to ski manufacturing. By removing unneeded layers in the front of the ski we make the ski lighter. This results in several advantages: the ski becomes up to 30 % damper, the ski feels more stable, edge-grip is more powerful, steering is more precise and the overall weight is reduced. Beginning this year, we are equipping all skis with the larger HOLLOWTECH 2.0 — with the size of each Hollowtech adapted to individual model lines. A larger design for even better performance.


Each Kästle ski is built with the finest wood core, manufactured with precision to one-tenth of a millimeter. This allows us to control the weight, responsiveness and dampening characteristics of the ski, resulting in a high-quality, durable product. The wood type, or combination of different woods, is individually catered to each model line, based on the ski‘s intended application. We guarantee unique handling with outstanding performance.

Sandwich-Sidewall Constrcution

We adapt our Sandwich-Sidewall Construction from alpine racing and consider this technology a distinguishing feature of all of our models. This design gives every Kästle Ski optimal flex and torsional rigidity, creating sensitive and direct power transmission and ensuring total control, even at high speed. For the TX98 we used the SEMI-CAP SANDWICH-SIDEWALL CONSTRUCTION, in which the top sheet protects the upper edge of the ski.

Elliptical Radius

Each model is designed to have its own carving characteristics, which is based on the ski’s intended application, by adjusting the radius along the waist of the ski. The shape of the Elliptical Radius determines how quickly and aggressively the ski enters and exits a turn.

Graphite Sinter Base

Kästle uses uncompromisingly high-quality UHM Graphite Sintered Bases, these are used in racing. The result: excellent sliding and wax absorption properties in a durable, long lasting base.


We build our skis with classic camber and distinguish between Standard Camber and Low Camber: With LOW CAMBER, the ski center is slightly elevated and the contact points are moved toward the ski center. The effective edge is consequentially less, and the ski is more playful and forgiving.

Shovel and Tail

With the shovel and tail design, we can refine the aggressiveness of our skis.

The HOOK FREE SHOVEL is a longer shovel that is often combined with Early or Progressive Rise. With this design the contact point to the snow is moved toward the center of the ski, thus ensuring a more forgiving and playful performance.

The HOOK FREE TAIL is often combined with Dual Rise and a longer tail, with the contact point being moved toward the center of the ski. The result is a forgiving, playful performance when exiting a turn.


With Rise technology, we optimize the shovel of the ski and control its float depending on the ski’s application.

PROGRESSIVE RISE optimizes float and easy turning in freeride and all-mountain freeride conditions.

DUAL RISE technology combined with an adapted Camber profile creates a ski which guarantees the best float, even in the deepest of snow, without losing responsiveness.
