The IST ProEar Mask is designed to counter most of the unavoidable effects pressure and water have on the ears, so you can have more enjoyable dive time.

Difficulty in equalising and the possibility of getting an ear infection are problems that can happen to any diver regardless of their experience. It can become serious enough to stop one from diving.

The IST ProEar Mask is manufactured to the highest standard and only the best materials are used. It is designed to counter most of the unavoidable effects pressure and water have on the ears so you can have more enjoyable dive time.

The soft silicone ear covers form a watertight seal between the ear drum and the cover. The pressure buffer created is designed to have the same pressure as your nasal cavity. When air is exhaled through the nose into the mask, it travels through the equalisation tubes.

Therefore, the ear pressure in the middle and outer area is the same and the "squeeze" from the outside pressure will be significantly reduced. Other benefits from keeping the ears sealed also include reducing the chance of an ear infection from water, plus improved sense of direction and warmth retention.

With one-way valves placed inside each tube, air is allowed to travel only from the mask to the ear covers for pressure equalisation and water clearance while stopping water from flooding the mask in the unlikely event of flooded ear covers.
