IST Pro Ear Mask RX007 Lenses Available

Quick answer: The IST Pro Ear is a dive mask with built-in watertight ear cups. A tube-and-seal system equalizes the air in the ear cups as you exhale into the mask, so water stays out of your ears, they stay warmer, and the ear-pressure ache many divers feel is reduced. A prescription lens option is available.

Fit note for bigger divers

This mask has to seal in two places: around your face and around each ear. IST doesn't publish a size rating for either, so fit matters even more than usual. Do the fit test below with the ear cups in place, and if you have a wide face or larger head, compare it against our wide-fit masks.

What it does well

For divers who deal with ear pain, swimmer's ear or frequent ear infections, keeping water off the eardrum is the whole point. IST says the dry ear cups also improve underwater hearing and your sense of direction. It works for scuba and snorkeling.

Before you buy

Talk to your doctor before diving if you have an ear condition. You still need to equalize your middle ears normally. Hold the mask to your face without the strap and breathe in gently through your nose; it should stay put without pressure at your temples or nose pocket. Read How to Fit a Dive Mask.
