Aqualung Air Dry Purge Snorkel is a bendable snorkel with a large diameter tube, has a purge reservoir with 2 valves, and is very flexible and durable thanks to the flexothane. Attaching the snorkel to a mask is quick and simple. Additionally, the Aqualung Snorkel has a comfortable silicone mouthpiece, a spray-proof end to limit the entry of water in the snorkel, and is overall an exceptional product. The Aqualung Air Dry Purge Snorkel is available in black, silver, lime, metallic blue, and translucent lime.
