IST's ProEar ME-80 is a dual-lens mask with a crystal-clear silicone skirt. But what makes the ProEar ME-80 unique is its pair of ear pods that provide a watertight fit over each ear. The air spaces inside these ear pods are connected to the air space inside the mask via a pair of equalization tubes. This makes equalizing easier for divers who have difficulty, and reduces the risk of ear infection by reducing the amount of water that enters the ears. It's available in six models, with features such as black silicone, prescription lenses and a kids version.
