Dude, it’s simple. The sun reflects off the water, hitting you from all angles. Without proper protection, you’re looking at a nasty burn that’ll ruin your next session, or worse, long-term skin damage. Think of it as essential as wax on your board. You wouldn’t paddle out with a slick deck, so don’t paddle out without your zinc or mineral-based sunscreen. Protecting your skin means more days in the lineup chasing that endless summer.
