The Vortex Snorkel from Seac Sub has a flexible hose on the bottom half with a purge valve that allows any water that gets into the hose to drain away without you breathing it in. The wave deflector on top of the hose will help to prevent water splashing into the hose and the oval design gives this snorkel a streamlined fit next to your head.
