The Dynastar M-Free 90 Ski is built from the get-go as a freeride weapon rather than just tweaking and modifying an existing all mountain ski. That’s why it features a Paulownia Core reinforced with a Fiberglass Torsion Box. Paulownia means Dynastar doesn’t need to resort to fancy inserts to reduce weight because there never was any, and the Fiberglass Torsion Box enhances the full-length wood core’s natural liveliness for strength and precision out of the underfoot camber. At either end the upturned Progressive Rocker enhances agility and helps make float easy to find even on the deepest days, while the Adaptativ Sidecut makes this ski a smoother ride with tuned edge engagement on hardpack.
