Extra Wetsuit features
Wetsuit manufacturers try to enhance the experience of surfers by introducing special wetsuit features such as glide-skin material around the neck of the wetsuit to prevent wetsuit rash or chaff without requiring the surfer to put on a rash vest underneath. Rip Curl introduced the Batwing system a few years back in their wetsuit to keep the surfer extra warm on their most critical part of the body, the torso. This is where the heat is generated and water leakage through the back zip threatens this warmth. So this batwing is an extra layer of thin neoprene that gives extra protection.
