The Aerobie Superdisc Ultra features a patented spoiler rim for long stable and accurate flights. The unique cushioned edge provides great grip and super soft catches. The Ultra is basically the same design as the traditional 10 Superdisc but its 12 diameter makes it heavier and increases distance and stability during flight. What's more this disc floats so you won't lose it to the sea or a river. Available in red/pink yellow green or blue.
