A great choice for free diving, the Seac Flash snorkel features an anti-splash top that effectively blocks water from entering the snorkel. It also includes an innovative purge valve system that sits below the mouthpiece for rapid emptying of water. The tube is constructed of durable PVC with bellows in liquid silicone, and its corrugated flexible hose allows you to manage the angle of the nozzle. It's complemented by a silicone mouthpiece that features a comfortable ergonomic fit with plenty of bite for teeth to keep your jaw relaxed.
