Polypro is a lightweight bouncy tubing which is perfect for hula hoops.
It is ideal for those who want to do hand tricks and waist hooping. It can be sensitive in the heat and cold. IE it can get hot and reshape in the car mid-summer, or it can shatter in the cold under 10 degrees. I can repair it in Vancouver, but shipping elsewhere will cost the same as a new hoop.
5/8″ is skinnier and lighter tubing. Stardust tubing is more sensitive to cold weather but is extra grippy on your bare legs in the summer! Designed to be used without grip tape!
