TUSA Ino M1011 Dive Mask
The TUSA Ino is a compact single-window mask designed with smaller faces in mind. If standard adult masks feel too bulky around your brow or cheeks, it is a useful model to try while keeping an open view underwater.
Features and benefits
- Smaller fitting profile: Offers a more compact option when larger adult masks feel oversized.
- Single lens close to the face: Provides a wide view in a low-volume design.
- 3D SYNQ fitting ring: Allows the silicone skirt to adapt as you settle the mask into position.
- Swift Buckle 3D: Lets you fine-tune strap tension for a comfortable fit.

Strap comfort and adjustment
The contoured 3D silicone strap follows the curve of the back of your head. Its split shape spreads contact over a wider area, helping the mask stay comfortably in position with light strap tension.
Fit guidance
The Ino is designed for smaller faces. Check for an even seal, comfortable frame clearance and enough space around your nose. Our Hallam team can help you compare it with other compact masks.

The fit classification follows TUSA’s 2026 skirt-fit guide. Check the seal, brow clearance and nose comfort on your own face; the fit label is a starting point.
Care and storage
Rinse your mask with fresh water after each dive or snorkel, flushing salt and sand from the buckles before adjusting them. Let it dry in the shade, then store it in a protective case away from heat, direct sunlight and coloured rubber gear that can stain the silicone.
For cleaning, use a diluted neutral cleaner suitable for masks and rinse it away completely. Avoid strong chemicals, abrasive scrubbing and flame treatment. Check the skirt, strap and buckles for damage before use.
