The Ocea is the first of its kind – an environmentally-conscious regulator made from recycled materials and bio-plastics, manufactured in a solar-powered facility. Based on the XL4+, every single material and process was reconsidered to create the most eco-sensitive scuba diving regulator in the world. The Ocea is a truly game-changing regulator that removes five times its own weight in plastic from the environment.To complement your eco-friendly XL4 Ocea regulator, this compact and lightweight second stage Octopus regulator improves comfort and helps reduce jaw fatigue when needed in an out-of-air emergency.
