Swiss brand Movement ("the freeski company") makes a full line of skis that include narrow carvers all the way up to powder fatties. The Logic X is the one model imported to North America from the X-Series, a group of super lightweight ski-mountaineering models designed for expert expeditioneers in challenging high-mountain environments. At 88mm in the waist, it's the widest of the series. We skied this model on a backcountry tour in Colorado and were very impressed that it had so much rigidity and integrity in a very lightweight package. It's torsion-box interior is designed to give superior edge grip.
