Is it necessary to use a low-temperature version of the polo in winter?

I have to. Bobball, also known as space ball, is a new extreme sport. Bobo ball consists of a plastic balloon filled with air, and there is a plastic ball with a diameter of 2 meters inside the balloon. Be sure to use the low-temperature version of the wave ball in winter. The summer model and the winter model can be used at different temperatures and are easy to explode or blow out.
