This is the king (or queen) of all snorkels. It has more features than you could shake a snorkel at. To start with it remains completely dry underwater, has a flexible hose to keep it out of the way of your regulator, replaceable silicone mouthpiece, purge valve, quick release clip, and finally it comes in a variety of colours to keep you from being a fashion disaster.
What more could you want from a snorkel? OK, free postage and packing.
