The Kastaplast K1 Glow Grym is a stable, speed 13 distance driver in K1 Glow Line plastic that lights up under any flashlight or headlamp.

Flight Numbers: 13 / 5 / -1 / 2

K1 Glow Line is a firm, durable blend with just enough give to feel comfortable on release, and the glow charges fast and holds long enough to finish a full round after dark. The rim runs a slim 2.2 cm, which keeps the disc from feeling bulky in the hand even at this speed.

Thrown flat with speed it turns over into a long, smooth S curve before settling into a controlled fade, which makes it a strong tailwind driver and a dependable option on wide open holes. It is stable rather than heavily overstable, so it holds up in a headwind without needing a huge arm behind it, and both forehand and backhand throwers get a clean release off the beadless rim. Intermediate players moving up from a fairway driver find it approachable, and advanced players use it as a straight up distance workhorse when the wind is not doing them any favors.
