Kastaplast / K1 Glow & K1/ Alva / Blue / | 11/6/-2/2

Flight Numbers:
11 / 6 / -2 / 2

The Kastaplast Alva is an understable distance driver built for effortless distance and smooth, controlled shot shaping. With plenty of glide and noticeable high-speed turn, it’s designed to flip up, ride long turnover lines, and push farther than expected without requiring max power. It’s approachable for intermediate arms but still useful for advanced players looking for workable distance.

In K1 plastic, the Alva features Kastaplast’s premium blend with excellent durability and a clean, slightly firm feel. It maintains its flight characteristics over time while offering a consistent release for both backhand and controlled forehand shots.

Best Uses

• Hyzer flip distance drives
• Long turnover shots
• Tailwind bombs
• Controlled distance lines

Real Talk

This is easy distance.

It wants to flip, it wants to glide, and it wants to go far without you forcing it. If you’ve ever thrown something and thought “that felt way too easy for how far it went,” this is that disc.

In K1 Glow plastic, the Alva uses a premium, durable blend with added glow and a slightly stiffer feel. This typically results in a more stable flight compared to standard K1 while maintaining long-term consistency and a clean release.

Best Uses

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

Real Talk

Same disc—just a little more disciplined.

• K1 = flippy, glidey, easy distance
• K1 Glow = still workable, but less likely to burn over

If you like the Alva but want it to hold together a little better when you step on it, this is the version you grab.
