Freedom Technology is a set of technologies to enhance fit and performance exclusive to Tusa. Freedom model masks feature a dimpled skirt surface with varied silicone thicknesses and stability ridges in addition to a proprietary low-friction skirt surface on the fitting line.

The buckle rotates a full 180 degrees to accommodate varying head sizes for optimum fit. The thin frame and rotation of the buckle allow the mask to be folded into a compact size.

Tusa's patented 3D Strap is a true three-dimensional design that snugly fits against the head’s natural curvature. The 3D strap offers unprecedented comfort and fit, unlike standard flat mask straps.

The Quick-Adjust Buckle System incorporates a newly-designed low-profile buckle. The result is a compact, lightweight, technologically advanced mask design that can be easily and quickly adjusted for a perfect fit.

Tusa's Round Edge Skirt features a proprietary round edge cross-sectionally shaped skirt. This rounded edge results in a soft fit that suppresses pressure and reduces creasing left on the face. The "planar fit, instead of linear fit" silicone skirt maintains great fit and unprecedented comfort.
