UnderPar Collection: Kastaplast K1 Berg Disc Golf Disc (Bird Berg)

The Kastaplast Berg has long been one of the most unique putters and utility discs on the market—trusted for its unmatched stability, feel, and precision touch. We loved the disc so much that we knew it needed a new identity in the Birdie Market. That’s how the Bird Berg was born.

This disc isn’t just another tool in your bag—it’s your secret weapon. With the Bird Berg, you’ll find consistency on approaches, confidence on tricky greens, and the control you need when others falter.

Should you keep this secret to yourself? Maybe. But then again… letting your friends and competitors in on the Bird Berg might just make your next round even more fun.

What Kastaplast say about the Berg

Berg is designed for distinct shots, where you don’t need to worry about the disc gliding far past the basket. The disc features an ergonomic thumb track which is prominent on the top side while not being noticeable at the bottom. This makes it feel very different from any other putter. Berg is Swedish for mountain.
