Suntrunk

Swim Protected. Glow Beautifully.

Swim trunks made from recycled polyester embedded with microcapsules containing a synthetic version of hippo sweat compounds — natural pigments that hippos secrete as antibiotic sunscreen. When you enter water, the trunks slowly release a visible red-tinted protective layer that forms an active UV-blocking barrier around your lower body, eliminating the need to reapply sunscreen to covered areas.

✨ The Wow Moment

You jump into the ocean and look down to see a beautiful red aura blooming from your trunks — like a drop of ink in water — creating a visible, shimmering shield that you can SEE protecting you from UV rays. Other swimmers gather around asking "what IS that?"
