The Atom is quite possibly the most fun disc to throw! Use the Atom for a fun game of catch with your friends, give your K-9 friend some exercise, or warm up for your next round! The Atom is slightly smaller than a regular golf disc at 7.25 inch (185 mm) in diameter and weighs 85 grams. The outstanding glide and comfortable feel in the hand will have you reaching for it every time you get a chance. Great for warm ups or in the back yard!
