Our bag material is made of an all-weather water resistant canvas material. It is the ideal fabric for both durability and long term playability. They feel great on the very first toss and get better with every throw. We have found pea rock to be the best fill. The pea rock is also very consistent in weight and mass from pebble to pebble, offering perfect bag balance. Available colors: Black, Blue, Brown, Gold, Gray, Green Burgundy, Purple & Red.
