Scubapro Escape Snorkel In its very simplest form, a snorkel is a bent tube that enables you to breath with your face underwater. Quite naturally, the configuration of that tube & the design of its components will determine its level of comfort during use. All SCUBAPRO snorkels are hydro-dynamically designed for ease of use. Elliptical barrel models cut through water with very little resistance, allowing unrestricted breathing & ease of clearing. Contoured models bend closely around your head to minimize drag. Semi-dry top models help prevent water entry into tube. All models incorporate specially-designed mouthpieces that conform correctly to your bite, & can be angled for maximum comfort.
