High quality Screamin' Orange® balls add a fun and engaging look to your fitness room. Seamless, roto-molded vinyl balls are designed to allow air to escape slowly rather than burst, even if the outer skin is punctured. Great for strength, balance, and stretching exercises. Tacky surface enhances control. Burst-resistant to 1,000 lb (454 kg), but supports static loads of up to 2,200 lb (998 kg).
