The Freestyle Snorkel is designed specifically for freestyle swimmers. This design allows swimmers to achieve a lower head position during freestyle and therefor further optimize body position. Not recommended for use with buttery or breaststroke training as tube may take water. Designed to use ceentrifugal force generated during flip turns to greatly restrict water from entering the tube. The Freestyle Snorkel will allow a swimmer to maintain a natural, rhythmic breathing pattern due to easy achievement of proper body position. The elimination of the purge valve requires in an increased lung capacity to clear water. Results in an increased CO2 tolerance and VO2 max from regular use. Fully compatible with cardio cap for simulated altitude training.
