The present technology relates to a snorkel which includes a breathing tube having a first end received in a mouth of a user and an upper opening in a second end opposite the first end. The snorkel further includes a housing around the upper opening which includes a slot. The housing and slot together trap an air pocket within the housing when the housing is submerged underwater, with the upper opening of the breathing tube positioned in the air pocket to prevent water from entering the upper opening.
