TUSA Freedom HD M1001 Dive Mask
The TUSA Freedom HD is worth trying if you prefer a larger mask frame and an open view underwater. Its single-window design pairs a broad lens with rotating buckles, so you can adjust the strap angle as well as its tension.
Features and benefits
- Broad single-window design: Gives you an open view for watching your surroundings and checking your dive equipment.
- Five strap-angle settings: Position the strap higher or lower to adjust where it sits against your head.
- 180° rotating buckles: The buckles move with the strap and fold inward for packing.
- Freedom Technology silicone skirt: Flexible areas and support ridges help the skirt sit comfortably against the face.

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 Freedom HD has a larger frame, but frame size alone does not determine the seal. Try the mask against your face and check forehead, cheek and nose-pocket comfort before choosing your fit.

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.
