This makes creating a mask one of the ultimate challenges. What works with one face, might not work with another. At TUSA we use advanced materials and technologies such as Computer Aided Design (C.A.D.) to create masks that deliver an unsurpassed level of fit, comfort, and beauty. TUSA masks are designed to provide a clear, wide field of vision and provide you with an unbeatable combination of style and state-of-the art technology. CRYSTAL SILICONE SKIRT: The double feather edged skirt of the mask is made of the highest grade crystal silicone to provide a snug, watertight fit while also delivering true comfort. WIDE COLOR SELECTION: TUSA's low-volume, high-visibility masks offer you a choice of fashion-able colors so your outfit can match from top to bottom. Most advanced design and light weight for comfort. POLY-CARBONATE FRAME: The frame of the mask is made of high density poly-carbonate which provides strong resistance against impact. QUICK-ADJUST STRAP BUCKLE: Non-slip double strap and quick-adjust spring-less strap buckles allow easy adjustments, even underwater.
