Snorkels are great but you tend to breathe in part of the air you just exhaled that didn’t get the chance to get out of the tube. The Powerbreather uses a system that consistently passes exhaled air and moisture to the outside so you only breathe in fresh air. It’s great for optimising your style, preparing for competition or muscular endurance training. It could also be used to get new swimmers comfortable in the water. An innovative valve technology prevents you from inhaling water.
