Protecting your kayak from exposure to sunlight when stored will lengthen its useful life. If it's outside, it can be covered or simply stored in a shady place.
We suggest you use a boat cover or some sort of fabric that is not plastic if you wish to cover your kayak. If moisture gets between plastic and your boat, it may discolor the kayak or weaken any vinyl straps. It is best to store your kayak in a clean and dry area when not in use.
