The K-10 Competition Standard is the official competition flying disc of the Hyperflite Skyhoundz World Canine Disc Championship Series — the largest canine disc competition series in the world. Hyperflite K-10 Competition Standard discs are not puncture-resistant. If your toothy canine quickly renders your comp standard disc unfit for flight, then you are a prime candidate for the revolutionary Hyperflite Jawz disc. Inspect discs regularly — discard if damaged. All Competition Standard-material discs feature Hyperflite's patent-pending X-Flash™ Anti-Glare Technology. Colors and design may vary from image.
