Our shelters and tarps have a variety of uses for protection from the elements when your in the great outdoors. Whether you're at the beach, floating, camping, or at a festival you'll always have a place to chill under. We do not test these products for specific SPF or UPF ratings, so unfortunately we can't know or give an exact number of what level of sun exposure this could protect you against. We do know that these products will provide you with some coverage any time during the day rain or shine!
