The TUSA Freedom Technology provides a superior fit and level of comfort by using an advanced silicone skirt design that incorporates a series of dimpled and ridged areas, varying silicone thicknesses as well as a low friction area for a better seal with reduced pressure and irritation on the skin.
This video helps to visualise these technologies:
TUSA Freedom Fit is the special areas that they have added to the silicone skirt design to either reinforce, improve flexibility or reduce the risk of leakage during a dive.
Key areas around the forehead and cheek bones have been designed with dimples which combine to increase the skirt’s softness, flexibility and skin surface contact. This also greatly reduces leakage and enhances comfort.
Varied Silicone Thickness:
A regulator or snorkel mouthpiece, when in use, can cause areas of the mouth and nose section to distort causing leakage and discomfort. Varied thicknesses of silicone in these key areas reduce leakage and provide a better fit.
As water pressure increases, a mask will compress inwards toward the face often causing further leakage or discomfort. Areas under the cheek bones have been reinforced with stability ridges to minimise this compression maintaining ideal skin surface contact.
The other element that goes into the TUSA Freedom Technology is Freedom Dry which enhances comfort and fit by utilising a revolutionary low friction skirt surface. The skirt fitting line (shown in red) includes a low friction surface that delivers a superior seal and increases the facial area contact patch while significantly reducing excess skin tension. The result is a soft and supple feeling mask with a dramatically improved seal.
