Welcome on the Montana page!
Montana is Gradient's new light weight mountain glider. Montana is expected to follow the success of our well known Delite glider that was in production for three years and has been most popular in this specialized sector of the market. Unlike Delite (a light-weight version of Golden), Montana has been designed as a "Lightweight Mountain Glider" from the scratch. Gradient aimed for a well balanced stability-performance ratio, high quality construction and overall "user friendliness". All these characteristics were successfully incorporated in the design of Montana. This glider offers similar performance as the Delite but with ~12% weight and packed volume reduction. Light 15mm wide risers with extra light Ronstan pulleys and specially shaped light-weight Peguet (Mailon Rapide) karabiners are included in the price and supplied as standard. Montana is made from the same Porcher fabric as Delite, with proven durability and strength. Montana has been certified both EN (B) and LTF (1-2).
