A skin-diving device comprising a dry snorkel with an improved valve. The device is useful for skin diving with a snorkel preventing water ingress and consists of a perforated plastic snorkel (G), a second, inner snorkel (F) made of flexible rubber and adhered to the inner surface of the first snorkel around each opening, and a curved top piece in the upper portion (AA) with an internal valve (B, C, D, E) which prevents water ingress from the top piece into the snorkel. Said device provides complete sealing of the snorkel regardless of the diver's position on or below the surface. Protection is also provided when the water surface is choppy.
