These hoops are extremely durable and perfect for exercise and weight loss, as well as general hoop practice. They would also be a great option to buy in bulk for the whole family or class! (If you want to buy more than 5, send us a message to discuss a discounted price!) These hoops are collapsible down to about 1/4 of their total size for easy travel and carrying!
