Kastaplast / K1 Vass / Glow / | 12/5/-1.5/2

Flight Numbers:
12 / 5 / -1.5 / 2

The Kastaplast Vass is a glide-heavy distance driver built for long, controlled flights with workable turn and a dependable finish. It’s designed to push forward with ease, offering a smooth S-curve flight when thrown with power while still being accessible for players who don’t have elite arm speed. It balances distance and control without feeling overly aggressive.

In K1 plastic, the Vass features Kastaplast’s premium blend with excellent durability and a slightly firm, grippy feel. It maintains its flight characteristics over time and provides a consistent release for both backhand and controlled forehand throws.

Best Uses

• Controlled distance drives
• Hyzer flip distance shots
• Long S-curve lines
• Tailwind distance

Real Talk

This is sneaky distance.

It’s not a max beef driver—it’s a “let it work” driver. You give it some angle, and it does the rest. If you like distance without feeling like you have to crush it, this is money.

In K1 Glow plastic, the Vass uses a premium, durable blend with added glow and a slightly stiffer feel. This typically results in increased torque resistance and a more consistent finish compared to standard K1.

Best Uses

• Controlled distance drives
• Hyzer flip to straight shots
• Long S-curve lines
• Night rounds

Real Talk

Same disc—just tightened up.

• K1 = glidey, workable, easy distance
• K1 Glow = more stable, more controlled

If you’ve ever had a distance driver turn a little too much when you stepped on it, this version fixes that without losing the glide.
