The Salomon S/Lab QST Echo Ski transforms the legendary QST 106 into a lightweight backcountry weapon that doesn't compromise on downhill performance. At just 1700-1940g per ski, this touring-specific evolution features a karuba and poplar woodcore reinforced with superlight basalt fibers and cork damping technology, delivering the responsive feel advanced skiers demand while keeping weight minimal for those grueling ascents. The 106mm waist width strikes the perfect balance for floating through powder and crud while remaining nimble enough for variable backcountry conditions, while the freeride profile ensures you can charge confidently down whatever line caught your eye on the way up. Whether you're linking turns through knee-deep powder or navigating wind-scoured terrain, the QST Echo's all-conditions design and titanium binding reinforcement make it a reliable partner for serious backcountry adventures where every gram and every turn counts.
