Clark Full Wetsuit - Reef 5/4mm
Clark Full Wetsuit – 5/4mm
Maximum Warmth for Very Cold Water Conditions
Clark is our warmest women’s full wetsuit, designed for cold to very cold water conditions where insulation and comfort are essential. With long sleeves and full-length legs, it provides maximum coverage while allowing controlled, confident movement in challenging environments. A thermal internal lining through the body panels helps maximise heat retention for extended sessions in very cold water.
The 5/4mm Clark is made from premium Japanese Yamamoto limestone-based neoprene, delivering increased insulation throughout the body for long winter sessions. Glued and blind-stitched (GBS) seams help minimise water entry and maintain core warmth, making this wetsuit well suited for very cold conditions. A back-zip entry ensures easy on and off before and after cold-water sessions.

Which Clark thickness should I choose?
Clark is available in 2/2mm, 3/3mm, 4/3mm, and 5/4mm thicknesses.
Choose a lighter thickness for warmer water and higher flexibility, and a thicker option for colder water and longer sessions. Refer to the Designed For section to help select the right level of warmth for your conditions.
Is Clark suitable for activities other than surfing?
Yes. Clark is designed for a wide range of water activities, including surfing, stand-up paddleboarding, wakeboarding, kitesurfing, windsurfing, snorkelling, scuba diving, open-water swimming, and foiling.
Does Clark feel restrictive in thicker versions?
Clark is designed to maintain comfort and mobility across all thicknesses. Thicker options provide increased insulation while remaining flexible through high-movement areas such as the shoulders and arms.
Is Clark easy to put on and take off?
Yes. Clark features a back-zip entry designed for easy on and off before and after sessions.
What materials are used in the Clark wetsuits?
Clark is made from premium Japanese limestone-based neoprene with recycled internal linings. Details about materials and environmental considerations can be found in the Materials & Environment section.
Does Clark have a thermal lining?
Clark 3/3mm, 4/3mm, and 5/4mm wetsuits feature thermal internal lining through key body panels to help retain warmth during cooler and colder water sessions. The 2/2mm version is designed for lighter insulation and does not include thermal lining.
How should I care for my Clark wetsuit?
Rinse your wetsuit with fresh water after each use, avoid prolonged exposure to direct sunlight, and allow it to dry fully before storage.
When not in use, close the Velcro® tabs to help prevent snagging or damage to the lining and stitching.
