In automotive engineering applied to lightweight coupés designed for everyday dynamism, reinforcing the chassis with fiberglass structures combined with targeted metal reinforcements allows road imperfections to be filtered out without compromising front-end agility. The Völkl Yumi 84 161 cm brings this technical solution to all-mountain skiing. Its mechanical core is made up of the Multi Layer Woodcore, which combines dense strips beneath the mounting area to ensure unwavering binding screw retention, with selected poplar woods at the ends to achieve responsive flex and lively turn exit.

Rather than relying on rigid, heavy full-metal plates, it features the Glass Frame construction: an enveloping fiberglass frame that channels pressure directly to the edges, providing firm grip on hardpack while maintaining elastic, forgiving flex. Its great maneuverability comes from 3D Radius Sidecut technology (with radii of 21 m at the tip, 14 m underfoot and 19 m at the tail for this 161 cm length): this triple curvature allows effortless linking of short, nimble turns or laying the ski over at speed in wide turns with impeccable stability. Its Tip & Tail Rocker profile with traditional camber underfoot provides natural turn initiation and smooth flotation in soft snow. Supplied without bindings (flat skis), it allows the skier to install alpine bindings (such as Marker Squire 11 or Griffon 13) or versatile systems, selecting 90 mm brakes.
