Stay super agile and flexible with the Synergy 4/3 Chest Zip Wetsuit. Forget the limitations of stiff and inelastic wetsuits. The wetsuit is made from partly recycled Superlight neoprene, a lightweight foam made in part from recycled car tires and neoprene scraps. The 100 % recycled Superflex jersey offers flexibility with high sustainability. The chest zip provides even less resistance when paddling, while the 4/3 mm keeps you warm in waters from 12 to 17 degrees Celsius.
