Cold water doesn’t stand a chance with Long Reef Surf Co’s premium range of 5mm wetsuits. Built for frosty surf sessions, diving adventures and deep water conditions, these suits are engineered to maximise thermal retention when water drops below 12°C. You might be braving bitterly cold Southern Ocean swells or heading out on a winter dive—either way, the 5mm wetsuit is your first and best line of defence.
5mm wetsuits deliver superior insulation with thicker neoprene throughout the core and crucial areas. These features are regularly combined with reinforced knee panels, thermal linings, and durable seam seals to lock in the warmth and keep out the cold. All of it makes the 5mm wetsuit a superior option for extended water exposure or high-contact sports like spearfishing and kitesurfing.
Despite the added thickness, modern innovations in wetsuit construction ensure these suits remain surprisingly flexible. Advanced stretch neoprene and articulated design features allow for comfortable movement, vital for active Aussie water sports. A properly fitted 5mm wetsuit should feel secure without noticeably restricting your range, creating a close seal that minimises water entry and maximises heat retention.
Of course, comfort isn’t just about warmth—it’s about wearability. Our selection at Long Reef Surf Co includes wetsuits with plush internal linings, easy-entry zip systems, and contoured cuts that move with your body, reducing fatigue and enhancing endurance.
Durable, comfortable, and built to handle the coldest Aussie conditions, 5mm wetsuits give you the confidence to explore deeper, stay out longer, and chase the biggest waves. For the serious surfer, diver, or winter wave chaser, nothing compares to the performance and protection of a 5mm wetsuit from Long Reef Surf Co.
