The Powerbreather allows swimmers to focus on their stroke and less on turning and straining their neck while taking a breath. This technology can also relieve some of the fears or apprehensions some swimmers may face and allows you to swim hard.
The Powerbreather works in a similar way to a snorkel in a sense that you can keep your head under water while still breathing. It takes it one step further with a new technology they have developed which blocks any water from entering the mouth or the top of the device.
