Kastaplast Alva (K1 Hard)
The Kastaplast Alva in K1 Hard plastic brings a firmer, more stable-feeling version of this high-speed, glide-heavy distance driver. K1 Hard offers a slicker, stiffer feel than standard K1, making it ideal for players who prefer a crisp release and premium durability. This blend generally adds a touch of stability to the Alva’s flight, giving power throwers a more torque-resistant option without sacrificing the disc’s signature glide and workable turn.
Flight Profile — 12 / 6 / -2 / 2
The K1 Hard Alva delivers the same long, drifting S-curve potential as other Alva plastics, but with a slightly firmer, more predictable finish. It flips up smoothly when thrown hard, glides for days, and then fades back with confidence—making it a standout choice for wide-open distance throws and shaping long fairway lines.
