Disc Golf Center says this about the U-Max:
The U-Max is a PDGA approved Ultimate Disc that is also great for playing catch.
The UV model changes to purple when exposed to sunlight.
The Reflyer is made from 60% post consumer recycled polyethylene plastic and looks cool with multiple colors throughout the disc.
The Night Glow is super bright and glows for a long time in the dark after charging in the light.  (hide)
