The arena Pro II swim snorkel is perfect for competitive swimmers who want to improve their swimming or breathing technique. The hydrodynamic design and the adjustable headband ensure a stable fit even at high speed. Since the swim snorkel allows breathing underwater, the athlete can focus entirely on swimming technique and water position. The interchangeable air regulators allow the air supply to be regulated, for two different strength lung workouts. Thanks to two different sized silicone mouthpieces, the swim snorkel is suitable for all swimmers.
