The Ergonomic snorkel breathing tube has the correct amount of flexibility, yet not too soft to create airflow interruptions. The diameter and length of the tube is optimized for natural effortless breathing and to make clearing easier. The hydrodynamic shape and mouthpiece orientation that swivels in relation to the breathing tube make this snorkel ideal for prolonged use during surface swims. The snorkel includes a position adjustable keeper for mask strap attachment that is also removable. Black color only.
