Kastaplast K1 Grind Berg - Putt and Approach Disc

The Kastaplast K1 Grind Berg is famous for its uniquely slow, ultra-dependable flight and unmatched control around the green. Designed to fly exactly where you aim it, the Berg offers extreme predictability with virtually no glide, making it a trusted choice for controlled approaches, confident putts and technical utility shots. True to its name - Berg, Swedish for mountain - this disc delivers rock-solid consistency in all conditions, especially in the wind.

Type and Recommended Use
The Berg is a stable to slightly overstable putt and approach disc built for deliberate, touch-sensitive shots. It excels on windy-day approaches, short controlled upshots and fearless putting where you need the disc to sit quickly without drifting or gliding past the target. Its straight flight with minimal movement makes it ideal for high-pressure situations close to the basket.

Flight Characteristics

Material and Feel - K1 Grind Plastic
K1 Grind is Kastaplast’s premium recycled plastic, made from 100 percent reclaimed K1 material. It offers the same durability, weather resistance and performance as standard K1 plastic, with a slightly firmer feel and excellent grip. Built to withstand heavy use on rocky and wooded courses, K1 Grind delivers sustainability without compromise.
