The Kastaplast K1 Glow Berg brings the same low glide, high accuracy Berg shape to night rounds, with just enough glow mixed into the K1 plastic to help you spot it after dark. It still refuses to skip past the basket the way every Berg does.

Flight Numbers: 1 / 1 / 0 / 2

K1 Glow keeps most of the firm, durable feel of standard K1 plastic, just a touch less slick when it is brand new because of the glow additive. It breaks in over time to a comfortable, dependable grip, and the glow itself is enough to find on the ground without needing a flashlight held right on it.

The Berg shape barely glides at all, so approach shots drop close to where you release them instead of drifting or skipping forward. On a full power drive it still will not go far, which is exactly the point on gusty nights when accuracy matters more than distance. It handles forehand and backhand releases equally well thanks to the low profile rim.

Good for night league players who want the Berg's pinpoint accuracy without giving up visibility, and for anyone whose misses tend to run long and need a disc that stops fast.

Want a softer, tackier feel? The K1 Berg in standard plastic breaks in a little differently. Prefer more grip for putting specifically? Try the K3 Berg. Browse our overstable putters.
