Mercury Free-X 4/3 from Prolimit, developed for surfing in cooler conditions with a focus on warmth, mobility and durability. The suit is made of double-liner NaturePrene2 based on oystershell, completely neoprene-free, with durable Neolight heather 550+ and Quad Flex on the outside for good stretch.
The inside is lined with Zodiac 2 and Thermal Rebound which effectively reflects heat back towards the body. The seams are sealed with Fluid Taping Method for increased tightness and comfort, and the chest-zip provides a flexible fit with free movement in the upper body.
A very good suit that has quickly become a favorite among windsurfers and kiters.
