The Madshus Annum 78 is the widest ski in the backcountry line with a deeper, progressive sidecut,that helps you turn smoothly. Its metal edges are there to boost your confidence off-trail. The Omnitrack waxless base lets you kick, glide, and climb during long tours through changing conditions. Its Multicore is a strong wood core laminated together to enhance the camber lifetime that gives extra strength and liveliness to the ski, and it is shaped to fit the ski profile, minimizing the excess use of glue in production. The Omnitrak base is engineered with five zones using round, spaced scales in transition zones for a smoother, more efficient glide and sharp, tight scales underfoot for maximum grip.
