Montana is Gradient's new light weight mountain glider. With Montana, Gradient follows the success of our well known Delite glider which has been in production for three years and which has been very popular in this is a specialist sector of the market. The Gradient Development Team decided on greater specialisation for the new light weight Montana. Gradient aimed for very well balanced stability-performance measures, a high quality construction and overall user friendliness. All these aims are clearly achieved in the Montana. Montana offers similar performance potential to the Delite but with greater (~12%) weight and volume reduction. Light 15mm wide risers with extra light Ronstan pulleys and specially shaped light-weight Peguet (Mailon Rapide) carabiners are standard. Montana is produced from the same Porcher fabric as Delite, with proven durability and performance.
