IST Sports Pro Ear Mask

The mask features a specialized tube and seal system that connects the mask's interior to the ear cups. As you exhale through your nose into the mask, air is channeled into the ear cups, allowing you to equalize ear pressure without needing to use your hands.

For the watertight ear cups to function properly, they need a direct seal against your skin. While you can wear a thin dive hood, you will likely need to cut holes in the hood around your ears to ensure the cups maintain a proper seal.

Yes, while the lens comes with an anti-fog film, it is still a good practice to use a mild anti-fog spray or gel before each dive. Avoid scrubbing the inside of the lens with abrasive materials, as this can damage the coating over time.

Surprisingly, yes. Because the ear cups keep your ear canals dry, you avoid the muffled sound caused by water entering the ear. Many divers find that this actually improves their ability to hear and determine the direction of sounds underwater.

This mask is primarily designed for scuba diving. Because the air volume inside the mask and ear cups is significant, it can be difficult to equalize the mask itself during deep freediving descents.

Ensure your face is clean and free of sunscreen or hair around the seal area. If you have facial hair, applying a small amount of silicone grease to the seal can help create a better barrier against water entry.
