There are few skis that have stood the test of time. The Concept is one that works. A high end dual concave tunnel with a soft flex pattern make it just as good now as it was in the late 80’s. Forgiving, smooth, consistent, performing at a high level every single set. The sweet spot is huge which is why so many thousands of skiers have fallen in love with this ski. The Concept is the definition of smoothness and consistency. The dual concave tunnel, which is a tunnel within a tunnel, helps the ski easily hold edge while crossing the wake. The nice big round bevels make edge transition smooth and flowing. The Concept is as reliable as the sun coming up tomorrow.
