DETAILED DESCRIPTION
The Mercury in C-Zip Version
The Mercury series is the foundation of Prolimit's winter range, described by the brand as its most versatile wetsuit. This version uses the same recipe as the Mercury Steamer Freezip 5/4: identical thickness, material, Zodiac2 lining, and seams. The closure changes. Prolimit rates it 8 out of 10 for warmth and 10 out of 10 for stretch.
Warmth: Thermal Rebound2 and Zodiac2
Inside, a Zodiac2 jacquard velvet fleece, lined with a quick-drying thermal fleece. It absorbs water from the skin and then quickly releases it. Between this lining and the rubber is the Thermal Rebound2 layer, derived from survival blankets: it reflects body heat and blocks cooling due to wind.
C-Zip Closure and FTM Seams
The C-Zip is a closure designed by Prolimit. Its symmetrical design distributes pressure evenly across the chest and follows the body's curve, with minimal water entry. FTM (Fluid Taping Method) seams are triple-glued and sealed on the outside by a black tape wider than the seam; on the inside, they are glued and blind-stitched. They remain waterproof without losing their stretch.
NaturePrene2 Oystershell
The rubber contains no neoprene. NaturePrene2 is made from 80% natural rubber harvested from FSC-certified plantations and 20% recycled carbon black from tires, enriched with oyster shell powder and soybean oil. The panels are assembled with water-based, solvent-free glue. On the exterior, the Quad Flex lining stretches in all directions, and its grid weave reinforces durability over time.

FAQ - PROLIMIT MERCURY STEAMER C-ZIP 5/4
This wetsuit is for riders who stay in cold water for a long time, whether for Kite, Wing, or Surf. The 5 mm torso keeps you warm, and the 4 mm on the arms and legs allows movement. We classify it as a men's winter wetsuit.
The closure is the difference. On prolimit.com, both 5/4 models in the Mercury series share the NaturePrene2 Oystershell material, Zodiac2 Thermal Rebound lining, FTM seams, and the same warmth and stretch ratings. The C-Zip is a symmetrical chest closure. The Freezip is a full-opening YKK frontzip.
The size guide above uses Prolimit's men's chart, including weight, height, chest, waist, and hip measurements. MT and LT sizes maintain the M and L measurements but with a taller height. If you are between two sizes, come try it on at the shop. Trying it on is better than a chart.
Rinse it with fresh water after each session. Dry it in the shade on a wide hanger, inside out first, then right side out. Avoid direct sunlight and heat sources; these will degrade the rubber and glued seams.
