CHECK THE SIZE CHART (in the image section above) Based on the Zone3 Evolution, the Mens Versa has been designed as a stripped-down version to give newcomers to Swim-Run a high performing suit at an entry-level price point. Different materials and flat-lock stitching have enabled the price to be brought down but without sacrificing functionality. The suit is designed for both swimming and running meaning that no kit changes are required, and combines a great fitting swim wetsuit with the benefit of high stretch leg panels for running and a front zip for lung expansion and breathability on the run.Back and underarm panels have been made from zone3's innovative Neo-Breathe TM fabric which is a very soft, 4-way stretch neoprene that allows moisture and body heat to escape while still protecting against the cold and water intake.  Highly durable Gator fabric on the legs offers protection against rugged terrain while an extended section covers the knees for added warmth and protection.  Features: Back and underarm panels made from our innovative Neo-Breathe TM fabric which is a soft four-way stretch neoprene and uniquely allows moisture and body heat to escape whilst protecting against the cold and water intake.  Bright coloured, high stretch 2mm shoulder panels for flexibility and visibility and Speedflo fabric on the front chest to reduce drag through the water.
