The Kastaplast Stal is an overstable fairway driver and is named for its toughness. Stal, the Swedish name for steel, was once a common soldier's name.
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.
