At Isurus, our passion is to build world-class wetsuits that stand up to the harshest conditions the ocean might offer.

Living and surfing in and along the California coast, a frequent topic of conversation was just how much wetsuit innovation had stagnated and quality had deteriorated. It is about designing a wetsuit that improves surfer performance. Click for more about Isurus.
