The Arena Pro III swimming snorkel is perfect for competitive swimmers who want to improve their swimming or breathing technique. The hydrodynamic design and adjustable headband ensure a stable fit even at high speed. As the swimming snorkel allows you to breathe underwater, the athlete can concentrate entirely on the swimming technique and the water position. With the help of the interchangeable air regulators, the air supply can be regulated for two different strength lung workouts. Thanks to two different sized silicone mouthpieces, the swimming snorkel is suitable for all swimmers.
