The O-Two is a forgiving, 75-mm-waisted frontside carver with a touch of terrain-smoothing tip rocker and an environmentally aware construction. It uses renewable bamboo for sidewalls, instead of the usual plastic, and linen fibers for core-reinforcement laminates, instead of the usual fiberglass. The Spirit Series is a collection of three narrow-waisted frontside carvers suitable for intermediate to advanced skiers who stick to the groomers. They're built for comfort and ease. Compared to the Laser series of expert-level carvers, they feature softer flexes and softer, less edgy sidewalls. All are metal-free constructions, for light weight and ease of use. All are built on full wood cores. Waist widths range from 66 mm to 75 mm. Stockli Skis, now 75 years old and under its third generation of family ownership, is based in Wohusen, Switzerland, near Lucerne.
