Polypro Hoops – simple, lightweight, & lightning fast – Polypro is an awesome material to hoop with! You can sand the inside of your hoop to add grip naturally. Some of our customers prefer to “eyeline” the inside of the hoop with a ½” strip of 3M clear grip tape. Choose between 2 connections: friction fit or a push button connector. It easily pulls apart and can be coiled into roughly half it’s normal size. All hoop diameters are measured by the inside of the hoop. Both UV and Natural colors are blacklight reactive.
