H3O

At H3O, caring for our oceans is at the heart of everything we do. 🌊 Our mission is to inspire people to make sustainable lifestyle choices that protect the planet and raise awareness about ocean pollution—and how it directly impacts human health. Studies by IPEN have shown that 75% of women in small island developing nations have mercury levels above 0.58 ppm, a threshold linked to neurological and developmental harm in unborn children. These alarming statistics remind us that protecting our oceans isn’t just an environmental issue—it’s a human one.

That’s why H3O merges purpose with style, creating wearable and shareable merchandise that sparks conversation and change. Our first collection features sleek, ocean-inspired pieces like our signature hat and “Leave No Trace” white crewneck, designed to make sustainability look good. 💙 A portion of every purchase goes directly toward ocean cleanup initiatives—so you’re not just wearing a brand, you’re making waves for a cleaner, healthier future.
