Review on Anti Fog Panoramic Breathing Circulatory Adults Black Black by Jimmy Jefferson

They offer an excellent field of vision and are crystal clear. The problem is that the rubber bands that wrap around the head are too elastic. When I exhale, the openings that release the air are sealed, so I have to exhale with adequate pressure. This sometimes causes the mask to bounce off my face for a split second, letting a small amount of water through. I think a stiffer headband (I tightened it but didn't help) would have prevented this problem. Also, if I go upstairs for air when I'm almost out of breath and inhale very quickly and deeply for air, some water will also enter through the openings around my mouth. This rarely happens and only when I'm really trying to get some air.
