Maximum Agility. Cold-Water Protection: The Shark Stop FLEX 5mm Hooded Steamer

Don’t let the cold, or the "what-ifs", shorten your session. The Shark Stop FLEX range is engineered for those who need high-performance mobility without leaving safety to chance. This 5mm hooded model is our ultimate cold-water solution, blending our signature bite-resistant technology with a high-stretch architecture.

Designed for the athlete who moves constantly, the FLEX range uses a specialized placement of protective material that allows for an unrestricted paddle and a natural range of motion, even in the heaviest conditions.

Why the FLEX 5mm Hooded is your cold-water essential:

• High-Stretch Safety: Features our UHMWPE fiber, a material tougher than steel, integrated into a design that prioritises flexibility so you can move, paddle, and dive without resistance.
  
• Integrated Thermal Hood: A built-in hood significantly reduces heat loss from the head and prevents "ice cream headaches" during duck dives and deep descents.
• Superior 5mm Insulation: Designed for cold-water environments (12–18°C), providing maximum thermal retention for those long, winter swells or deep-water explorations.
• Minimal-Flush Chest Zip: The streamlined front-entry system and hood virtually eliminate water flushing, keeping your internal temperature regulated in freezing conditions.
• Impact & Abrasion Resistant: Beyond shark protection, the FLEX material acts as a rugged shield against reef cuts, foil strikes, and gear abrasion.
• Eco-Engineered: Built with premium materials designed to withstand the harshest elements, ensuring your suit lasts longer and stays out of the landfill.

Backed by Science

Trust is built on evidence. Our bite-resistant technology is the result of years of 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 FLEX 5mm Hooded right for you?

• Cold-Water Surfers & Divers who need maximum warmth, and maximum flexibility in temperatures below 18°C.

• Foilers & Kiteboarders in cold climates seeking protection from both sharks and high-speed foil strikes.

• Winter Explorers who want the security of a bite-resistant barrier without the bulk of a traditional "heavy" suit.

• Anyone looking for the ultimate combination of warmth, flexibility, and peace of mind.

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.
