The Powerbreather, a sealed snorkel for swimmers

The Powerbreather is an advanced breathing system for swimmers, designed to decrease apprehension in beginners and increase focus and performance among advanced swimmers. Essentially a sealed, watertight snorkel, an intake valve located on the back of the head allows the swimmer to take in fresh air while a second valve pumps exhaled air completely out, the device designed to keep all water out, so that breathing remains unimpeded. And it puts a smile on your face. Via gizmag
