The Psycho RG8 features O'Neill's EXCLUSIVE environmentally friendly UltraFlex RG8 Neoprene. The O'Neill Psycho Re•Generate Series takes the best aspects of our incredible ZEN Zip closure found in our Psycho wetsuits and uses this same technology in a front-zip entry. The 2012 FUZE closure system has an easier entry and exit, along with added warmth using RG8-Air Firewall. Tested by O'Neill's most intense team riders in the most frigid waters across the globe.
