Kastaplast Berg K1 Glow - 173 g

The dye on this Berg is a yin-yang of worlds — one half glowing teal and aqua, soft and luminous, the other a rich, bubbling swirl of copper, bronze, and deep brown, like something ancient and molten. The two halves meet in a jagged, organic boundary that looks like coastline from above. The crown stamp sits cleanly over the divide. Under UV light, the K1 Glow plastic charges up and the teal half blazes. Hand-dyed, completely unique.

The Kastaplast Berg is one of disc golf's most celebrated overstable putters — a disc with a cult following for good reason. K1 Glow plastic is Kastaplast's premium glow formulation, offering a firm, confident grip and brilliant UV reactivity for night rounds. At 173g, it's built for authority. Flight numbers 1|1|0|2 make it a specialist: it holds any line you put it on and finishes hard, making it the go-to for spike hyzers, windy approaches, and any shot that needs to stop right where you land it.
