The Dynastar E 4x4 5 is an awesome option for intermediate to advanced level ladies who want to expand their horizons on the groomers. The core incorporates Paulownia which gives a lighter weight feel than other woods used for better maneuverability and natural liveliness. A combination of Titanal Inserts and Basalt Fibers energizes the core for good response and stability when you're carving. The 3D Profile Technology reinforces key areas in the ski for better power transmission starting from the center of the ski out into the tips and tails.
