3mm FLEX Chest Zip Wetsuit Steamer | Shark Stop

Performance Without Limits: The Shark Stop FLEX 3mm Chest Zip

Move with total freedom. Focus on the ride. The Shark Stop FLEX is our lightest, most agile design, engineered specifically for athletes who demand peak performance. If you prioritize maximum flexibility for explosive paddling and high-speed maneuvers, the FLEX range is your perfect match.

By strategically integrating our bite-resistant technology into a high-stretch architecture, we’ve created a suit that feels like a premium performance steamer but offers a vital layer of safety that traditional neoprene suits simply can't provide.

Why the FLEX 3mm is your performance essential:

• Elite Flexibility: Designed with a specialised placement of UHMWPE fiber that allows for an unrestricted range of motion. It’s tough on the outside, but incredibly stretchy where you need it most.

• Scientifically Proven: The FLEX range features the same independently tested material proven by Flinders University to prevent 100% of critical injuries in tiger shark trials.

• Minimal-Flush Chest Zip: The streamlined front-entry system creates a watertight seal that virtually eliminates water flushing, keeping you light and warm without any added bulk.

• The Perfect 3mm Balance: Optimized for moderate water (18–25°C), providing the ideal blend of temperature regulation, buoyancy, and a "second-skin" feel.

• Multi-Sport Versatility: Beyond shark-bite mitigation, the high-tensile fabric acts as a rugged shield against reef cuts, abrasions, and foil-strike injuries.

• Sustainable Performance: Built with premium, long-lasting materials designed to survive the salt and sun longer than standard wetsuits.

Backed by Science

Performance is nothing without proof. Our technology is the result of peer-reviewed research and real-world testing:

“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 FLEX 3mm Chest Zip right for you?

• High-Performance Surfers who need total freedom of movement for paddling and aggressive turns.

• Foilers & Kiteboarders looking for lightweight, high-stretch protection from both sharks and sharp foil injuries.

• Divers & Swimmers in moderate water who prefer a more athletic, streamlined fit.

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.
