The Tusa ViewTrek Plus Mask features a rounded cross-section skirt seal. The resulting soft fit suppresses pressure and reduces creasing left on the face. This "planar fit, instead of a linear fit" silicone skirt maintains a great seal and unprecedented comfort.

The area between the lenses on the Tusa ViewTrek Plus Mask is wider, enabling the entire mask frame to be moved closer to the face, creating a wider field of vision, without touching the upper nose.

The Tusa ViewTrek Plus Mask is the optimal product for divers who wish to enjoy underwater photography. The new construction means the entire mask frame is closer to the face, so that when the diver focuses the camera, it feels closer to how it does with the naked eye.

The strap angles on both the left and right sides can be varied, and then secured with the adjustor. This enables the up/down and left/right pressure on the face to be delicately adjusted.
