About Sustainability

We have eliminated the shoulder seams in this minimalist design for a seamless look, better fit, and undisturbed print!

Ocean-inspired clothing for the people who love the ocean as much as the ocean loves them.

Surface Interval was created out of our passion for the ocean, and sustainability is at the heart of everything we do.

Each month we help plant minimum on 36 coral fragments.

All of our products are crafted in small batches and limited quantities. This approach helps us maximize usage and reduce the risk of microplastics. Plus, our eco-friendly packaging is plastic-free, reusable, and recyclable.

Our rashguard is made from materials that once threatened marine life—single-use plastics, ghost nets, and recycled ocean waste.
