Rottefella's Back Country bindings are especially designed to perform in difficult conditions, where durability and control count the most. Innovative technologies, like sturdy closing mechanisms and wide binding plates, contribute to the optimal combination of performance, durability and comfort, for demanding expeditions and long trips.

NNN-BC Manual bindings offer a stronger and more secure boot to binding connection than the automatic binding so if you're serious about your off-trail skiing choose the NNN-BC Manual or it's big brother the NNN-BC Magnum for your skis. Like all NNN-BC bindings, the Manual bindings are wider for more stability and stronger than regular NNN bindings to withstand the rigors of off trail skiing. The integrated "Steering ridges" ensure maximum ski control and the flat heel plate provides stability in off-trail situations. The Rottefella NNN-BC binding system is the only heavy-duty back-country system binding currently on the market and works with a wide range of boots from light touring boots to the Alpina Alaska Heat heated all leather back-country boot.
