Solid disc in super lightweight form, 121g on our copy that's definitely going to be a lock in my wife's bag. The plastic is base which is fine, considering it's aimed towards new players. It's a nice rubbery DX but slightly nicer type plastic. If I rip on it, it turns over but holds surprisingly well before doing so.The whole zero gravity series is great except I wish the design was a little bit better and gave more prominence to the actual disc name AND show the flight numbers. I understand not having the flight numbers to make the disc less intimidating, but as first glance the whole series will look exactly the same since the stamp showcases the zero GRAVITY more than the actual disc name. The series also all only coming in all the same colors makes it even more confusing for beginners. We have a fuse and saint already in the same color and side by side it's not an easy or quick for a beginner to distinguish between them.End of the day, the price is nice, Explorer is a great mold. This gets borderline unusable on a harsh wind but that's the name of the game. Hope we can get some premium lightweight discs soon.
