Orca Vanir Flex Wetsuit Designed specifically for SwimRun events, Orca’s Vanir Flex Wetsuit offers a great range of movement when in the water and on land thanks to the Yamamoto 39 neoprene. A DuraSkin 2 outer fabric on the lower torso prevents the neoprene from getting damaged and there is a large rear pocket to carry race day supplies. The zip is situated on the front of the wetsuit so that it can be easily pulled down for cooling during the run and zipped back up when entering the water.
