A breathing system designed to allow Atlanteans to travel out of water for long periods of time.
Most Atlanteans can only survive out of water for about 10 minutes without artificial aid. Therefore, when an Atlantean ventures into the surface world, they wear a sealed bubble helmet that covers their head and neck-gills. The helmet is designed to enable the wearer to see and breath normally. A small cylindrical backpack recycles and renews the water. The system enables the wearer to stay away from the water for days before they suffer ill effects.
