Full-face snorkeling mask S/M No name L21B — full-face diving mask, size S/M

Full-face snorkeling mask S/M No name L21B covers the eyes, nose and mouth to provide an unobstructed single-pane field of view and an integrated breathing system for surface snorkeling and shallow free diving. The top-mounted snorkel tube connection allows combined inhalation and exhalation through the mask, enabling hands-free swimming and clearer vision compared with separate snorkel-and-mask setups. Size S/M is intended for recreational users with medium facial dimensions.

Advantages

The full-face construction eliminates the need for a separate mouthpiece and offers a wider peripheral view through a single curved lens. Integrated breathing channels separate inhaled and exhaled air to reduce fogging during normal snorkeling conditions. The top snorkel connection helps keep the breathing airway above water while the mask seal around the face provides a simple, single-piece fit for easier donning and doffing.

Suitable for

• Recreational surface snorkeling
• Shallow free diving and snorkeling excursions
• Hands-free underwater observation and photography from the surface
• Casual swimmers seeking a wider field of view

Key specifications

• Fit size: S/M for medium facial dimensions
• Viewing area: single curved lens for wide peripheral vision

• Breathing system: integrated inhalation/exhalation channels with top snorkel tube connection

How to use

Before use, check the silicone skirt and straps for damage and confirm a clean, dry lens. Adjust the head straps to achieve an even seal around the face without excessive tension. Place the mask over your face, ensuring the nose and mouth are fully enclosed, then tighten straps incrementally until water ingress is prevented. Enter the water gradually, keep the top snorkel connection above the surface when breathing, and clear any splashed water by exhaling forcefully through the snorkel route if required.

Usage recommendations

Use the mask for surface snorkeling and shallow dives only; avoid deep scuba diving or activities requiring pressurization control. Rinse the mask with fresh water after each use and dry thoroughly before storage. Do not modify the breathing components or seals. Children should use full-face masks under adult supervision and ensure correct fit before entering the water.
