The K9 Hybrid series frames are 360 degrees improvement over our exisiting K9 series. We call it the hydrid becuase the rubber tip has been replaced with a metal tip, with Samvette icon embossed in gold, matte black or chrome. The metal tip, creates a snug fit, improves the strength of the frame and ensure the frames not only look cool but work just as good as the high end ones. Our K9 hybrid frame is made from a improvised premium high quality polycarbonate grade plastic, using a double injection mould process. This ensures that the K9 series frames are extremely ruggard, flexilble but highly comfortable and lightweight.So there you have it..our 2010 K9 hybrid- represents a unique combination of plastic and metal components to create a much better frame.
