Neoprene is ideal for ball stretchers. It’s stretchy yet strong, comfortable to wear for extended periods of time, and easy to put on. And if you’re into watersports, neoprene is your ideal choice; it won’t get damaged and is easy to clean. This cost-effective, 1.25 inch diameter vinyl / rubber material gives you multiple size options with a variety of length options. Neoprene also lasts longer and is more durable than silicone.
