IST Sports Corona Mask

Unlike temporary sprays or gels that wash away over time, the integrated film is permanently bonded to the lens. This provides a consistent, long-term solution to fogging without needing to reapply treatments before every dive.

Yes, the IST Corona is compatible with optical lenses. If you require vision correction, you can replace the standard lenses with prescription-ready options designed for this specific frame.

A low-volume mask sits closer to your face, which reduces the amount of air required to equalize pressure as you descend. It also brings the lenses closer to your eyes, which naturally expands your field of vision.

The soft silicone skirt is designed to be highly adaptable and creates a reliable seal on a wide variety of facial profiles. However, as with any mask, fit is subjective; the silicone is flexible enough to contour comfortably to most users.

Swivel buckles allow the strap to move independently of the frame. This flexibility helps the mask maintain a comfortable seal even when you move your head, and it makes it much easier to adjust the strap tension while wearing gloves.
