The TUSA Freedom HD Mask is the latest design to come from freedom technology. It is a single lens mask with an incredibly wide field of vision. This mask boasts a 180 degree rotational buckle system, which allows it to fit a variety of face sizes while maintaining a low-profile. Freedom technology is a set of revolutionary features offering superior fit, comfort and performance. The Freedom HD is one of the first next generation TUSA masks offering this innovative new technology combined with superior design, built quality, materials and frame construction. Freedom model masks feature a dimpled skirt surface with varied silicone thicknesses and stability ridges in addition to a proprietary low friction double feathered edge skirt surface on the fitting line. The quick-adjust buckle system incorporates a newly-designed low-profile buckle into the clear or black silicone rubber skirt of the mask. The result is a compact, lightweight, and technologically advanced mask design that can be easily and quickly adjusted for a perfect fit and folded into a compact size. 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, you won't have ring-around-the-eyeballs" like with other masks. TUSA's patented 3-D wide split strap is a true three-dimensional design that snugly fits against the head's natural curvature. The 3-D strap offers unprecedented comfort and fit unlike standard flat mask straps. The strap and the unique buckle allows a 5-position strap angle adjustment for micro-adjustment fine tuning. Mask has an easy-to-reach one hand nose pocket for ear equalization which can be utilized even when wearing thick gloves. Mask is available in multiple colors, and comes with a protective mask box.
