Simply breathe out through your nose and any water that has accumulated in your mask is forced out through a one-way purge valve. Once the mask is clear, the valve seals shut.PANORAMIC VIEW: Panoramic View masks feature a variety of designs offering an incredibly wide field-of-view. Several designs incorporate minimum frame volumes, domed side-windows, reduced frame structures as well as three and four window styles for maximum vision.ROUND EDGE SKIR: TUSA's Round Edge Skirt features a proprietary round edge cross-sectionally shaped skirt. This rounded edge results in a soft fit that suppresses pressure and reduces creasing left on the face. The "planar fit, instead of linear fit" silicone skirt maintains great fit and unprecedented comfort.
