Founded by 11-time world champion surfer Kelly Slater, the Freaks of Nature Daily Defender Sunscreen is a lightweight, fast-absorbing daily SPF. It’s water- and sweat-resistant, thanks to a formula that provides about 40-minutes of staying power before you need to re-apply. The Daily Defender Sunscreen also supports your skin’s microbiome all day and is reef-safe—so no worries about it causing adverse effects. We keep one of these in our backpack pockets at all times.
