Claim:
A snorkel, comprising: an elongate breathing tube having an upper portion and a lower portion, a lower opening formed in the lower portion and an upper opening formed in the upper portion; a mouthpiece formed at the lower opening; a one-way valve disposed in the lower portion, the one-way valve oriented to prevent the flow of fluids through the valve into the lower portion, but to permit the flow of gases and fluids through the valve and out of the lower portion; a check valve disposed in the upper portion, the check valve including a plate pivotable from an open position permitting airflow through the upper opening, and a closed position preventing airflow from the tube through the upper opening; and a splash guard including a cup member on an upper end of the breathing tube, and a sliding member longitudinally slidable on the breathing tube into contact with the cup member upon submersion of the splash guard so as to substantially prevent passage of water between the cup member and the sliding member.
