Full-Face Snorkeling Mask Bestway Flowtech S/M — adult size, 225×165×420 mm

The Bestway Flowtech full-face snorkeling mask in size S/M is designed for adult recreational snorkeling and coastal exploration. It offers an expansive 225 mm viewing area within overall dimensions of 420 × 225 × 165 mm and covers the nose and mouth in a single-piece construction to allow natural breathing while on the surface. The mask is supplied in a full-color retail box and sold as a single unit suitable for calm-water inspection, swimming near the surface, and casual open-water use.

Advantages

The mask uses one-way airflow technology to separate inhaled fresh air and exhaled air, enabling natural breathing through both nose and mouth. Full dry top technology helps prevent water entry into the snorkel when submerged, and a purge valve allows easy clearing if water does enter. The soft silicone full-face structure provides a comfortable seal and supports pressure equalization during shallow dives, while an adjustable elastic nylon strap ensures a secure fit. Materials are non-latex and non-PVC based.

Suitable for

• Recreational surface snorkeling and coastal sightseeing
• Calm-water inspection of shallow reefs and rock formations
• Casual open-water swimming and snorkeling near the surface

How to use

Before entering the water, adjust the elastic strap so the mask sits securely and comfortably on the face, forming a full seal around the perimeter. Place the mask over the face covering nose and mouth, then tighten the strap evenly to avoid pressure points. Attach and position the snorkel tubes according to the mask assembly instructions. Float on the surface and breathe naturally through the mask; inhale through the snorkel and exhale through the separate exhaust path. If water enters the snorkel, use the purge valve to clear it by exhaling firmly while upright at the surface. To equalize pressure when diving slightly below the surface, pinch the nose area or perform standard equalization techniques while descending gradually.

Usage recommendations

Use the mask in calm, surface-level conditions and avoid strong currents or deep free-diving. Inspect seals and straps before each use, rinse the mask with fresh water after use, and store it in a dry, shaded place away from direct sunlight. Do not use the full-face mask for SCUBA diving or situations requiring a separate breathing gas supply.
