The FINIS Original Swimmer's Snorkel Pink allows swimmers to concentrate on body balance, head position and stroke technique by eliminating the breathing cycle rotation. Breathing through a snorkel while swimming increases the capacity of the lungs to expel air, increasing the optimal intake of oxygen. Features Regular snorkel training increases CO2 tolerance and VO2 max. When used together with the cardio cap, the Swimmer's Snorkel provides benefits associated with altitude training. Patented front-mount design Swimmer's Snorkel can be worn with any standard swimming goggle. View a Product Demo of the FINIS Swimmer's Snorkel
