Full-Face Snorkeling Mask Master MAS-B601-XS Blue — Size XS, full-face design, integrated snorkel

The Master MAS-B601-XS Blue full-face snorkeling mask in size XS covers the eyes, nose and mouth to allow natural breathing through both nose and mouth while observing shallow-water environments. Its integrated dry-top snorkel is designed to minimise water entry at the surface, and a separate breathing chamber reduces fogging by directing exhaled air away from the viewing window. The mask provides a wide field of view suitable for coastal snorkeling and recreational use.

Advantages

The full-face design enables natural breathing without a separate mouthpiece and improves comfort for short surface swims and scenic observation. The integrated dry-top snorkel reduces the risk of water entering the snorkel when waves or splashes occur. A divided internal chamber helps limit lens fogging and keeps the viewing area clearer. The mask seals around the face to prevent leaks when sized correctly and offers an unobstructed panoramic view compared with traditional two-piece masks and snorkels.

Suitable for

• Recreational coastal snorkeling
• Shallow-water observation and swimming
• Beginners or users preferring mouthpiece-free breathing
• Short surface snorkel sessions and guided shore tours

Key specifications

• Full-face construction covering eyes, nose and mouth
• Integrated dry-top snorkel to reduce water ingress at the surface
• Separate internal breathing chamber to minimise lens fogging
• Panoramic single-window design for an expanded field of view
• Silicone skirt and adjustable straps for a face seal and fit
• Size: extra small (XS) indicated for smaller face shapes

How to use

Select the XS size to ensure a proper seal against the face, then adjust the silicone skirt and straps so the mask sits comfortably without gaps. Before entering the water, perform a dry fit and breathe normally through the mask to confirm airflow and fit. At the surface, breathe through the nose and mouth as you would on land; the dry-top snorkel helps prevent water from entering. If the mask takes on water, surface, remove the mask and clear it according to standard full-face mask clearing procedures before reuse.

Usage recommendations

Check the fit on land and in shallow water; ensure hair and facial hair are clear of the silicone skirt to improve the seal. Use this full-face mask for surface snorkeling and coastal trips rather than deep diving. Rinse with fresh water after each use and store in a dry, shaded place away from direct sunlight.
