Brightonkelp Mariner cold-water wetsuit 4/3mm in deep black neoprene, laid flat on weathered Brighton beach planks at low tide

Developed over two seasons of dawn swims off Hove lawns. The Mariner uses 4mm panels through the core and 3mm in the arms and legs for warmth without sacrificing reach. Flatlock seams sit flat against the skin to reduce chafe on long swims; a YKK back zip with an inner gusset keeps cold flushes to a minimum.
