Technical info:
The new ski touring models from Stereo are fibreglass constructions with a visible wooden core. The turning radius is short in front and longer further back. It has a long and low elliptical rocker tip. They have done a good job in reducing weight per surface area, but since this is one of the longest and widest skis in the test, the total weight is still almost 2 kg.

On snow:
As the name Polar Bear indicates, this ski is solid and ferocious rather than light and elegant. It is not particularly easy to turn with, but once you get it going it floats effortlessly on any surface. Polar Bear is best suited for experienced and slightly heavier skiers.
