Discraft has been a staple in disc sports since before most of us knew what a hyzer was. Founded in 1979, Discraft started with a focus on Ultimate Frisbee and quickly became the #1 manufacturer of Ultimate discs in the United States. But they didn’t stop there.

Discraft shifted into disc golf and quickly became one of the sport’s biggest names—currently holding the title as the second largest disc golf manufacturer in the U.S., behind only Innova. What sets Discraft apart isn’t just their plastic blends or world-famous discs—it’s their elite pro team, featuring some of the top male and female players on the planet, including multi-time world champions.

Every Discraft disc is proudly manufactured in Michigan, where the company continues to innovate with new molds, plastics, and collaborations that keep the game evolving. Whether you're an amateur, a league regular, or a touring pro, Discraft has discs that are built to perform at every level.

If you’ve ever picked up a Discraft disc and noticed a fifth number on the flight rating—congrats, you’ve just stumbled into one of the quirks that makes Discraft unique.

Let’s start with the basics. Most disc golf brands (following Innova’s lead) use a four-number flight rating system:

Speed – How fast the disc must be thrown to perform as intended.

Glide – How long the disc wants to stay in the air.

Turn – How much the disc drifts right (for RHBH throws) during the high-speed portion of flight.

Fade – How sharply the disc finishes left at the end of its flight (again, for RHBH).

In the early days of disc golf, Discraft didn’t use that system at all. Instead, they had just one number: the stability rating.

So what is the Discraft stability number?
Discraft’s stability rating is a standalone measurement that indicates the disc’s overall flight tendency:

0.0 is neutral – it flies straight with minimal turn or fade.

Negative numbers (like -1.0) mean the disc is understable, so it turns right more easily for RHBH throws.

Positive numbers (like 1.0 or 2.5) mean the disc is overstable, finishing left and resisting turn.

This stability number is the “fifth number” you'll often see on Discraft discs, and it’s still part of their branding even though they’ve officially adopted the four-number system in the past several years.

So if you see five numbers on a Discraft disc, just know that the last one is their original stability rating, giving you a little extra insight into how the disc will actually fly—especially helpful for those who’ve been throwing Discraft since before ratings were even a thing.

If you’ve ever scrolled through a list of Discraft discs and wondered why there are so many plastic options… you’re not alone. In fact, Discraft offers more plastic variations than any other disc golf brand, with over 170 different plastic types listed on InfiniteDiscs.com alone!

So what’s with all the plastic? The answer lies largely in the Ledgestone Open—the biggest tournament on the Discraft calendar and one of the biggest in the sport. Every year, Ledgestone serves up an avalanche of limited-edition, fundraiser discs in experimental plastics to help raise money for the event. These runs aren’t just marketing—they often showcase unique blends, flex variations, and eye-catching swirls that give collectors and throwers alike something new to chase.

But what are all these plastics, really?
Despite the long list, most Discraft plastics fall into two broad families:

TPE-based plastics – These are used in base blends like Putter Line, Soft, and Jawbreaker—great for putters and lower-cost discs.

TPU-based plastics – Most of Discraft’s premium plastics fall here. They’ll vary in flexibility, grip, and look depending on the additives used, but they’re all variations on the same core material.

The most common Discraft plastics you’ll run into:

Z Line – Super durable and often translucent. Built for long-term performance.

ESP – Premium feel with great grip and stunning swirls.

Big Z – A slightly stiffer take on Z Line with large, comic-style stamps.

And if you're into the latest drops, Fuzed Line and Mega Glow are two new standouts this year—Fuzed for its blend of durability and flex, and Mega Glow for, well, glowing like a UFO during your glow rounds.

So yeah, it’s a lot—but that’s kind of the point. With so many plastic options, you're bound to find the exact feel, flex, and flight you love.
