Our reversible tops are designed to keep up with all your adventures in and out of the water, whether you’re engaging your inner mermaid at sea or your core on a yoga mat, and everywhere in between! Kelps represent the largest species of algae in the world, with some, like the giant kelp, exceeding 100 feet (30 meters) in length. Giant kelp is also one of the fastest-growing organisms in the ocean, growing up to 2 ft per day! Gas-filled bladders beneath the kelp’s blades, called pneumatocysts, float the kelp towards the water’s surface, while the holdfasts keep them anchored in place, creating the iconic forest-like appearance. 5% of sales will be donated to the Smith Seaweed Ecology Lab at UC San Diego’s Scripps Institution of Oceanography to support their work on kelp forest ecology and restoration.
