The BC2 is the back inflation evolution of the acclaimed Atomic Aquatics BC series. The Atomic Aquatics BC2 incorporates the same futuristic, incredibly tough, corrosion-resistant materials as the jacket-style BC1. A result of the Atomic Aquatics “design studio” approach, the BC2 is a radical design departure from conventional back inflation BCs and is the TOUGHEST BACK INFLATION BC in the world.
