How does the protective layer of the suncover work? And what does the SPF factor 50 mean?

The protective layer of the suncover is an additional layer of fabric that we have specifically chosen for its UV ray-resistant properties. SPF (Sun Protection Factor) 50 is a term associated with sun protection products, such as sunscreens. It is a benchmark and indicates that the sun protection product provides a high level of protection against the sun's harmful effects, especially against UVB rays (ultraviolet B rays). The effect of the sunscreen fabric is similar to applying sunscreen with SPF 50.
