The Most Evolved & Protective Sharksuits Available

For many years I have studied the reactions of different species of sharks to the color, contrasts and composition of dive gear. Into the late 90s, I was building, testing and demonstrating suits primarily in open ocean areas.

More recently while working on reef and other inshore environments, the shiny or bright steel appeared in some instances to attract some sharks during testing and feeding scenarios. In these cases it may have been more difficult for the sharks to distinguish between divers wearing shiny suits and the often light-colored scraps of fish that were used as bait to attract and manipulate the sharks into feeding behavior.

Within our rapidly growing global shark diving industry, most observation and shark feeding facilities operate in relatively shallow water, or on the bottom within established areas and protocols, to provide as safe as possible an experience for their guests and professional feeders.

It became obvious that in those environments and conditions, with some species, a low key appearance with fewer or no bright shiny parts was less attractive to the sharks, which may consequently provide safer interactions for both sharks and divers.

Throughout his 35 years designing and building the sharksuits that are currently in use worldwide, Jeremiah was constantly experimenting and asking his suppliers for better, stronger materials. The steel used in earlier suits was obviously strong enough to get the job done but the welds with earlier alloys needed improvement. SharkArmor now benefits from those years of pushing, experiments and effort with our stronger steel, deeper welds and lighter weight ‘BlackMaille™’.


State of the Art SharkArmor™ Sharksuit Technology

SharkArmor’s workhorse Stainless Steel and Titanium Sharksuits along with our new low profile BlackMaille™ continue to represent the State of the Art in injury protection for professional divers worldwide. With a nearly forty year history of limiting or entirely preventing bite injury, Jeremiah Sullivan’s Sharksuits remain the Professionals Choice within the underwater Film/Photography, Scientific, Military, Rescue, Commercial Salvage, Aquarium, Zoo, Conservation and Consumer sectors.

40 Years of Sharksuit Innovation

In the late 1970s, marine biologist Jeremiah Sullivan developed a flexible suit of armor for divers to wear while working around sharks and called it the sharksuit. Since then, it’s been referred to as metal mesh sharksuit, chainmail anti-shark suit, steel mesh sharksuit, neptunic sharksuit etc. but they all originate with him. In 2012 Jeremiah left Neptunic in the past to establish a new, more evolved brand. This new venture represents the renowned capabilities in protective solutions for the diving community that Sullivan has provided for the past 40 years, in addition to new protective technologies and materials for a wide range of hazardous activities.

As part of that commitment, Jeremiah continues to integrate his three+ decades of unique direct experience in shark research, anti-shark bite technologies, solutions and skills into the most functionally effective sharksuits and other protective gear available. Many of the sharksuits designed and built by Jeremiah and his team continue to protect lives of professional divers on a daily basis the world over. This legendary work with anti-shark bite protection has proven instrumental in the development of the global shark diving industry, and remains the world standard among those who must work in hazardous circumstances with sharks in the open sea since 1978.
