A regulatable pressure goggle mask having a lens and a regulating structure is provided. The lens includes a viewing area and a regulating pressure area disposed under the viewing area. The regulating structure is disposed in the regulating pressure area and includes a support unit and two recesses disposed adjacent to the two sides of the support unit. The two recesses extend to two sides of a nose of a user respectively, and are formed by a first soft material.

A diving mask system is disclosed comprising a faceplate having a lateral partition on an interior surface delineating an upper and lower section, the lower section comprising a region that extends away from the upper section and includes at least one cutout section fitted with a complementary-shaped flexible insert that enables a user to grasp the nose. The faceplate further includes a flexible tubular insert defining a passageway extending through the faceplate to a lower chamber. The tubular insert has a distal end dimensioned to fit and seal onto the mouthpiece receiver tube of a conventional second stage scuba regulator permitting the mask to be scuba enabled. A quick-release clasp mechanism attached to the mask's elastic retention straps is also disclosed.

The faceplate further includes a rigid annular support frame either bonded to or extending out from a backside of said flange, the frame being configured within the outer periphery of said flange. A flexible annular sidewall skirt is attached to the support frame. The flexible skirt includes a lateral nose piece section attached to the partition. The lateral nose piece section having an inlet aperture and check valve for inhaled air, and an orifice through which an exhalation conduit having a separate check valve extends from the lower chamber to a snorkel device forming a passageway for exhaled air to pass through the upper chamber to the snorkel device. A quick-release clasp mechanism attached to the mask's elastic retention straps is also disclosed

A nose plug for performing a pressure equalization maneuver while underwater diving may include a base, a first nasal insert, and a second nasal insert. The first nasal insert and/or the second nasal insert may project from the base. The first nasal insert may fit snuggly within and may protrude deeply into a first nostril of a user when in use such that airflow through the first nostril is prevented. The second nasal insert may fit snuggly within and may protrude deeply into a second nostril of a user when in use such that airflow through the second nostril is prevented.

A breathable mask includes a main frame, a transparent lens portion, a water-sealing skirt and a breathing tube. The main frame includes a lens frame, a mouth frame and a nose frame interposed therebetween. The water-sealing skirt is integrally formed by an eye skirt, a nose skirt and a mouth skirt, and a skirt frame is arranged in front of the eye skirt. The transparent lens portion and the skirt frame are embedded in the lens frame in a water-sealing manner, and the nose skirt protrudes outward from the nose frame. A purge valve is provided between the mouth skirt and the mouth frame. The mouth skirt is adapted for one-way fluid communication to the outside through the purge valve and the mouth frame.
