This reef colour is a perfect Chocolate mousse, so Yum! Made out of 100% Japanese limestone based super stretch neoprene in 2mm and lining recycled from post consumer plastic bottles, to tackle plastic Ocean pollution.. We chose to manufacture with Yamamoto Limestone neoprene because it has the lowest carbon footprint in the modern wetsuit production. The use of limestone neoprene is an effort to make wetsuits as green as possible.
