Dry ski slope produced in a darker green (such as in Kendal Ski Club in Cumbria, England) to comply with planning requirements. There is no indication from NorCal Extreme Sports that AstroRide has been commercially tested to any great extent. The latest arrival is from UK company Proslope who produce a matting with variable filament lengths to emulate the gradual edge grip and release of snow. As with some other surfaces, the system is coloured white, is modular, and works both with and without a misting system. Dry slope users often improve the performance of their equipment by using the hardest grade of
