Tusa Geminus Mask for Diving and Snorkelling

Tusa Geminus Mask for Diving and Snorkelling, instantly more comfort and fit, noticeable as soon as the mask is put on. Another innovative design consistent with TUSA's forward thinking technical team. This mask has been created for divers wanting superb vision combined with a low volume design, lightweight yet rugged frame, and providing enhanced comfort and clarity of vision.

The Tusa Geminus mask features a silicone skirt shaped to reduce pressure on the face virtually elimating possible creasing/marking after the mask is taken off. The fit and comfort of this skirt is noticeable the instant the mask is put on.


The mask strap buckles are also mounted on to the side skirt of the mask - producing an extremely light to touch, easily adjusted strap/buckle system.

The Tusa Geminus Mask strap has also been designed to provide the most comfortable fit by following the occipital curvature of the head. Non-skid backing and superior hold ensure a secure and comfortable fit.

Price includes a FREE protective storage box

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.


Corrective Lenses are offered on several styles of masks. This option allows the diver to choose right and left lens powers in both a variety of diopters for maximum flexibility and for a custom fit.


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.

About Tusa


TUSA was founded by Kazuo Tabata in Tokyo, Japan in 1952. From the first handmade mask and goggles built in Mr. Tabata's garage, Tabata products have always been constructed using the finest and most advanced materials and innovative design techniques to produce premium diving and snorkelling products.

TUSA is a byword for quality in scuba and snorkelling circles and as far as we are concerned, you can't go far wrong with any of the TUSA kit.
