Atomic Theory Ski - Men's: The Award winning Theory joins the all new Vantage Series by Atomic. With Backbone Carbon technology the Theory is an extremely versatile all-mountain twin-tip. The innovative carbon insert runs the length of the ski like a stabilizing axis, increasing pop in turns. The result: the skis are easier to control – even at higher speeds. The All Mountain Rockers in the tip and tail make the Theory especially compliant, while the Step Down Sidewall increases edge grip for reliable turns on hard terrain.
