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.

Each Kästle ski is built with the finest woodcore, 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 choice of wood is determined by the desired properties of the ski in terms of stiffness, grip, stability, and weight. If the final product is to be stable, we choose a wood with a higher density, such as poplar or beech. A ski that should convince its rider with lightness and float, usually contains a lighter wood, such as paulownia. In many cases, however, we use a combination of different types of wood to meet all requirements. These are glued together and only then pressed with the remaining layers. By the way: we need a good 20,000 liters of glue per year for this. To put that into perspective, that's 11,511 full bathtubs.
But why wood anyway? No other substance can provide the ski with the desired handling characteristics as well as this material - and retain them over a longer period of time. It is quite simply THE quality feature, which is why not only every Kästle has a wood core, but special attention is paid to its origin in the selection as well. Thus, we use up to almost 80% domestic woods, whose main supplier is located in Switzerland.
 

To be able to further vary the riding characteristics of our skis, additional titanal, carbon or fiberglass inserts are used.

Titanal promises damping, stability and optimal power transmission. So it's no surprise that we use this material in a large number of our skis, since Kästle stands for maximum smoothness at high speeds.

Carbon is one of the most multifaceted materials. Exceptionally resilient and with the lowest weight, it is extremely interesting for ski construction. We use it mainly for our touring skis.

Glass fiber is characterized by its high elasticity. Usually this material is used together with carbon inserts to achieve the perfect combination of stability and flexibility.

The base, as the coating of the running surface, is another essential component of our skis and is largely responsible for their gliding properties. In our skis we mainly use a fast racing base, which consists of over 35% recycled material.

Kästle topsheets are made of special TPU or polyamide. For products that need to be a bit more robust - such as our freeriders or children's skis - we use a corundum protective surface.

Our TRI-TECH construction combines three innovative technologies to reduce weight while maximizing stability, power transmission and float: 3D Shape, Triple Woodcore & Titanal.

We have adopted our SANDWICH-SIDEWALL construction from alpine racing and it is a distinguishing feature of some of our models.

This method of construction gives Kästle skis optimum flex and torsional rigidity, creates sensitive and direct transfer of power and ensures total control, even at high speeds.

We build our skis with classic camber and distinguish between Standard Camber and Low Camber.

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

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