Extrem ski tech

We build every pair of Extrem Skis in our own ski factory just outside of the ski town of Åre, Sweden, driven by an endless passion and 100% renewable energy. We want your skis to last for many winters to come, and be a trusted friend on your adventures in the mountains, be it at home or far away. For that reason, we've been extremely (!) picky when choosing the materials and suppliers we work with to ensure the highest possible quality and the maximum longevity of our skis. When choosing an Extrem ski, you can trust that you choose Swedish quality from start to finish, with the highest regard for the environment and our co-workers.  

Wood cores


Our light-weight skis are made from a knot free, vertically laminated wood core of snappy poplar and light-weight paulownia. This combination of wood gives the ski a playful, lively and nimble character. A CNC-milled and integrated 55x650 mm plate of beech wood makes for a secure mounting of the binding.


The knot free, vertically laminated wood of snappy poplar is a medium lightweight core that gives the ski a playful character. Combined with Titanal the ski becomes stiffer and more torsionally rigid while keeping its liveliness. Without Titanal the ski is just super playful. A CNC-milled and integrated 55x650 mm plate of beech wood makes for a secure mounting of the binding.


A knot free, vertically laminated wood core of snappy poplar and stable beech gives a playful yet dampened character of the skis. Combining this with Titanal gives the ski performance, calmness and a superior edge grip. Without Titanal the wood core is more flexible and forgiving with more allround characteristics.

Prepreg glass and carbon fiber

We are quite unique to use dry Prepreg epoxy resins instead of letting our employees handle liquid epoxy when building skis, which is otherwise practice in the ski industry. Our glass and carbon fiber rolls come industrially impregnated with HexPly M78 from our supplier Hexcel, a world-leading producer of advanced composite material for the aerospace industry. This results in a dry and safe work environment for our ski builders while significantly increasing the quality of the skis.


To increase performance in terms of superior edge grip and high-speed stability, we add 0,4 mm Titanal to the construction on certain ski models. Titanal is the highest strength aluminium-alloy manufactured in an industrial standard process, originally developed for the aerospace industry. Titanal is a registred trademark, owned and produced by AMAG Austria Metall AG.

Full width Titanal – Project

Two layers of Titanal with the same width as the ski gives a superior edge grip and a high level of torsional rigidity on hard and icy snow. Used in the Project series.

Tapered Titanal – Reload

The Mothertree 105 Reload and Fusion 105 Reload use two layers of 67mm wide Titanal underfoot that tapers off to 30mm in the ends, near were the ski's rocker starts. This gives a good combination of stability and dampening without the ski becoming to torsionally stiff and grabby in the tip and tail.

Race rubber dampening

To minimize vibrations in hard snow conditions, such as icy slopes and wind packed off-piste, we use 1,5 mm race rubber dampening in the tip and tail from Austrian Haberkorn GmbH in selected ski models. We also use 0,2 mm rubberfoil in the skis to further strengthen the construction and increase the bonding between different materials.


To reduce the swing weight of selected ski models we use the ultra-light material Tubecomb in tip and tail. These cylindrical tube structures were invented for the aerospace industry as the ultimate energy and vibrations absorber. The material also happens to be very lightweight.

Extra thick steel edges

For maximum durability of our skis, we purchase one piece steel edges from the well renowned Waelzholz GmbH, who have manufactured steel edges in Germany for over 50 years. We use their extra thick and durable Profile 132 that is 2,3 mm high and 2,2 mm wide for all models except Fusion 95 Carbon Ultra, where we use a 1,9 mm high and 1,5 mm wide edge to minimize weight.

Extra wide ABS sidewall

For maximum durability of our skis, we use extra wide 8,5 mm ID 2500 ABS sidewalls from Austrian Isosport GmbH. The industry standard width is otherwise 5-6 mm.

Durable top sheet

For best wear performance and abrasion resistance, we use sublimated 0,55 mm Isocap ICP 8210 top sheets with a structured surface from Austrian Isosport GmbH.
