The Prolimit PF2 Free-X ecological wetsuit for men is the most sustainable wetsuit ever made. This wetsuit is one of the few FSC approved wetsuits, which means it is an environmentally appropriate product but is still made with the best technology available. This wetsuit is made to keep you warm, with its 6mm neoprene you can be sure that even in winter, you won't get cold. This year the wetsuit is also available in a 4mm edition.
