Total Confidence, Maximum Ease: The Shark Stop CORE 3mm Back Zip

Don’t let anything hold you back from the water. The Shark Stop CORE Back Zip combines our highest level of bite-resistant technology with the classic, easy-entry design preferred by many divers and ocean enthusiasts. While the CORE range is built for those who prioritize maximum protection, the Back Zip model adds a layer of convenience, making it easier than ever to gear up and get in.

By doubling down on coverage in the torso and critical impact zones, we’ve created a bite-resistant wetsuit that feels like armor but maintains the classic feel of your favorite steamer.

Why the CORE Back Zip is your ultimate ocean companion:

• Military-Grade Protection: Crafted with UHMWPE fiber, the same material found in aerospace and ballistics, to create a barrier that’s tougher than steel but light enough to move in.

• Scientifically Proven: Independently tested by Flinders University on Great Whites and Tiger Sharks, our material is proven to reduce critical injuries by 100%.

• Easy-Entry Back Zip: Features an extended pull-cord for effortless self-donning and a wide entry point, perfect for those who want a quick, hassle-free transition from the shore to the sea.

• Internal Flush Guard: Designed with a protective inner skin behind the zipper to minimize water flushing, ensuring your core stays warm even during long dives or sessions.

• The Perfect 3mm Balance: Optimized for temperatures between 18–25°C, providing the ideal blend of insulation, buoyancy, and abrasion resistance.

• Planet-Conscious: Built to last. By using ultra-durable materials, we reduce the need for frequent replacements, making it better for your wallet and the ocean.

Backed by Science

We believe safety should be based on data, not guesswork. Our technology is backed by rigorous, peer-reviewed research:

“Our findings suggest that lightweight bite-resistant materials integrated into traditional wetsuits designs offer a promising [...] approach to reduce injuries, haemorrhaging and tissue loss from the species responsible for most fatal bites globally.” — Clarke et al (2025)

Is the CORE Back Zip right for you?

• Surfers & Divers who want maximum coverage with the familiar, easy entry of a back-zip design.

• Foilers & Kiteboarders looking for heavy-duty protection from both sharks and sharp foil-strike injuries.

• Divers & Spearfishers who appreciate a wider entry point for easy gear changes on boats or beaches.

• Ocean Professionals who need a rugged, reliable "final line of defense" for daily use.

Sustainability: Closing the Loop

We’re committed to making our gear last, and keeping materials out of the ocean and landfill. Through our partnership with CircularFlow, we close the loop by transforming wetsuit offcuts and end-of-life suits into new, valuable materials. This ensures our resources stay in use, and out of the environment.

Liability

Wearing a Shark Stop wetsuit will not reduce the likelihood of a shark bite or prevent death by shark bite. 

We encourage people to wear a Shark Stop wetsuit when working in, or enjoying the ocean, in order to reduce the extent of bodily injury caused by shark bite.

The materials used in Shark Stop wetsuits are designed only to reduce the extent of skin and soft tissue penetration caused by shark bite and Shark Stop wetsuits provide no protection from the pressure impact of a shark bite (eg. bruising, crushing and/or breaking of bones and other bodily damage) or from drowning caused by shark bite.

While extensive testing has been performed in the development of the materials used in Shark Stop wetsuits to reduce the degree of bodily injury caused by shark bite, Shark Stop wetsuits must not be considered as a life saving device and Shark Stop accepts no liability for personal injury and/or death resulting from the use of Shark Stop wetsuits.
