A wooden beach umbrella is useless if it doesn't offer you the highest level of sun protection (UPF50+/over 98 percent UV Protection), so make sure the one you choose does. The interior of most wooden beach umbrellas will have a silver lining, which provides the majority of the protection from harmful UV radiation. Having said that, it's still crucial to continue using sunscreen and wearing polarized sunglasses even being covered by a wooden beach umbrella because of the way that sunlight is reflected off the sand and ocean. https://outdoorgearreviews.org/best-wooden-beach-umbrella/
