Grym is the Kastaplast disc for long smooth s-curves and tailwind bombs. A distance driver with a clean shape and a comfortable 2.2 cm rim. It'll hold the line you put it on and get you far down the fairway.
K1 Glow has an excellent feel. It is moderately grippy, but not too sticky. This plastic is extremely durable, making it perfect for regular day time rounds as well as night rounds. Kastaplast's Glow blend is one of, if not the brightest glowing plastics on the market.
