Need a basic bare hoop? Natural HDPE hoops are opaque white and have a simplistic look. Great for decorating! Measured in OD/Outside Diameter, hoops include a single push button connection and will be shipped disconnected and partially coiled down. HDPE has a spongier feel/bounce to it, is only slightly heavier than polypro, but is more durable in cold temperatures making it ideal for many more projects, hoops for kids and LED hoops
