The soft, silicone ear cover forms a watertight seal to maintain equal air pressure between your ear canal and the air inside the cover. Every exhale from the nose passes through the tube to the ear cover via a one-way valve, maintaining constant air pressure. If it feels like pressure is building in your ears, just exhale through the nose to instantly equalize. Soft, supple, hypoallergenic silicone skirt offers a snug, yet comfortable fit that hugs facial contours while providing an ample nose pocket for easy exhales. The dual-layer ProEar hood, specially designed for use with ProEar masks, is available for separate purchase.
