A basic snorkel consists of a curved tube with a mouthpiece. This is called a "J" snorkel, and an example is pictured to the left. Another common design is a flex snorkel. These snorkels allow the mouthpiece to hang away from the face while not in use.

Snorkel keepers secure the snorkel to your mask strap, and are available in several styles. They are included with all snorkels, and you can purchase replacement keepers to use as a back-up.
