If you want to extended service life of our watersports tube. It is not enough to simply fill it up and go! If you leave a full tube sitting in the sun for any length of time, it will expand. If you rent the tubes on the beach and have no place to store it in the shape, please do one thing, to let some air out everyday.
Don’t let it sit on the beach, dock, or boat full of air all the time!
At the same time, if it is stored out of the sun in a cool place, or put in to cool water, you may need to add air.
Heat expands, cold contracts. Check and adjust inflation levels each time before you use your tube.
You’ll have more fun, and your items will last longer.
