For the women in the world who demand light weight and outstanding performance in the splitboard world. The women's Pro Arc features Carbon reinforced nylon highbacks, full Pebax plastics, 7075 aluminum heel loops, 7075-T6 aluminum pivot pins, and seven custom made screws and hardware pieces. All this allows for the Arc to maintain an extremely light weight design and the highest performance of split board bindings on the market. Spark R&D spent day and night under the microscope to make every piece of this binding thinner and durable at the same time. Thanks to the material used, they were able to get away with a much lighter binding that rides like the original Arc we have all come to enjoy day in and day out.
