IST Pro Ear Mask

The mask features two silicone ear cups connected to the main mask body by tubes. When you exhale through your nose into the mask, the air pressure is equalized through these tubes into the ear cups, allowing you to equalize your ears without using your hands.

To maintain a proper watertight seal, the silicone ear cups need to sit directly against your skin. If you have long hair, you will need to pull it back or use a swim cap to ensure the seal isn't compromised.

While the lens comes with an anti-fog coating, it is still good practice to use a standard defogging solution or a quick spit-and-rinse before each dive to ensure maximum clarity throughout your session.

No, this is a standard dual-lens mask and is not designed to accommodate prescription glasses. If you require vision correction, you would need to look for a mask that supports custom optical lenses.

This mask is primarily designed for scuba diving. Because the ear cups add significant volume to the mask, they can be difficult to clear during the rapid descent and ascent typical of freediving.

The ear cups are positioned on the sides of the mask, so they do not obstruct your forward view. However, they do slightly limit your extreme peripheral vision compared to a low-profile, frameless mask.
