The Prolimit Mercury Free-X 6/4 Hooded 2026 is a high-performance men's winter wetsuit built for very cold sessions. A 6 mm body and 4 mm arms/legs combine maximum insulation with the mobility needed for wingfoil, windsurf, kitesurf and surf.
The integrated hood helps reduce heat loss around the head, neck and throat. Prolimit's FSC-certified NaturePrene2® construction is 100% neoprene-free, while the Free-X asymmetric chest entry is designed to reduce flushing without sacrificing freedom of movement.

Cold-Water Performance
Thermal Rebound™ adds a heat-reflective layer between the outer material and inner lining to help retain body warmth and reduce wind chill. Zodiac2 plush fleece and quick-dry inner materials improve comfort during long winter sessions.
Free-X Entry
The asymmetric Free-X chest entry uses a YKK zipper layout that opens on one side for a secure, low-flush fit while still making entry and exit practical.
FTM Seams
Prolimit's Fluid Taping Method combines glued seam construction with an external flexible seal. The result is a durable, watertight seam system designed to retain stretch.
Quad Flex
The Quad Flex outer fabric stretches in multiple directions while its woven texture adds durability for demanding use.
