TUSA Freedom Tri-Quest M3001 Dive Mask
The TUSA Freedom Tri-Quest adds domed side windows to a wide front lens, giving you a more open view to the sides. It is an option to consider when seeing more of your surroundings matters more to you than choosing the smallest mask.
Features and benefits
- Front and side windows: The three-window layout expands your view around the edges of the mask.
- Reduced frame structure: Keeps more of the viewing area open between the windows.
- Freedom Technology silicone skirt: Combines flexible contact areas with support ridges around the seal.
- Contoured strap and quick-adjust buckles: Make small strap adjustments to find a comfortable position.

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
Check the seal and nose-pocket comfort when choosing your mask. The Tri-Quest has a larger internal volume than many compact two-window masks, so consider that alongside its wider viewing area.

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
What’s included
One TUSA Freedom TRI-Quest Mask with fitted strap in the selected version. A snorkel, corrective lenses and other accessories are separate purchases unless expressly included in the selected package.
Compatible cleaning products
For standard uncoated mask glass, TUSA TEC52 anti-fog treatment is an option when permitted by the mask and treatment instructions. For a separate neoprene strap cover, if you use one, we recommend Cressi Neoclean Wetsuit Wash or Revivex Wetsuit Shampoo to clean compatible neoprene. Wash that component separately according to its care label and the cleaner’s dilution instructions, then rinse thoroughly and dry in the shade. These neoprene cleaners are not a recommendation for the mask lens or a regulator assembly.
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.
