Technical info:
SGN from Sogn in Norway launched Tunnelvisjon prior to last season, but we haven´t been able to test it before now. It has been developed in collaboration with Asbjørn Eggebø Næss. It has a long rocker and taper in both ends, and there is relatively little width difference between the front and the back ski. Here you have a lot of back ski. The flex is average, with a somewhat softer tip.

On snow:
A modern big mountain ski that thrives above the treeline. This ski clearly stands out in the test. There is a lot of back ski, and it feels like you are positioned quite far in front compared to the other skis in this test: The result is that it is easy to skid with at high speed. In other words, it is easy to maneuver. The disadvantage is that it is a little heavy and, on chopped snow, it is less predictable to turn with. It is not designed to be playful and the edge grip is not particularly good - this is a big mountain weapon.

This sequence of numbers indicates stiffness. Each number corresponds to a part of the ski, from tail to tip. 5 equals the average
for this part and length of the ski. Lower values indicate softer skis, higher values stiffer.
