The Kastaplast K1 Glow Reko takes Kastaplast's stable putt and approach disc, the Reko, and molds it in a glow blend that holds up once the sun drops. The Reko flies straight with barely any turn or fade, and the glow additive does not change that flight, just how long you can still see the disc after dark.

Flight Numbers: 3 / 3 / 0 / 1

K1 is Kastaplast's premium base plastic, firm out of the box with enough grip to trust a spin putt in wet grass. Glow K1 charges under sunlight or a headlamp and holds its glow through a good chunk of a twilight round, and it beats in at the same slow pace as the standard K1 line, so the disc you buy today still feels new next season.

Thrown flat it holds dead straight with a small check at the end, no early turn even on a firm putt. On approach shots it sits down quickly instead of skipping past the basket, and it will hold a gentle anhyzer line if you need to work around a tree. Beginners get a putter that will not surprise them, and anyone who plays late leagues gets a disc they can actually find in the grass.

Want the same flight without the glow additive? The K1 Reko is the daytime version in identical plastic. Prefer more grip and a softer beat-in? The K3 Reko is the tackier K3 take on the same mold. Browse the whole Reko lineup for every plastic Kastaplast makes it in.
