X-VU Stylish & comfortable• Tri-comfort Skirt• 2-button buckles on the skirt• New Bi-silicone X shaped strap The front portion of the X-vu skirt has a series of horizontal “bumpers” made to absorb any relative movement between the mask & the face. This diminishes the sensation of squeezing on the face & the forehead, which can be especially appreciated during long dives. The new X-shaped strap improves the overall fit of the mask. The two-button buckles allow for a quick & effortless strap adjustment.
