Stamp color may vary. Disc colors are assorted. Matty O has been around the block a few times, and the man knows smooth. He remains a tour staple thanks to his control and ability to precisely dissect course after course after course. One of his latest tools is the M4, with its incredibly workable flight at any angle. His trademark high release is always clean and meshes beautifully with the silky smooth flight of the M4. Support Matt Orum directly with one of his 2020 Signature Series M4s in 500 Plastic. 500 Plastic has been in development for quite some time, formulated and based on carefully considered player feedback. It has a stiffer, less gummy feel than 400 Plastic. This provides an extremely confident grip on the flight plate, balancing just the right amount of flex and firmness, with a very solid feeling rim that we believe disc golfers are going to love. 500 Plastic has a uniquely pearlescent finish, unlike anything else in the Prodigy Disc plastic line.
