Review on Keystand Full Face Snorkel Mask With Breathing Mechanism And Crystal Lens - 180° Panoramic View, Anti-Leak, Anti-Fog, Detachable Camera Mount Included by Emmanuel Winschel

I am so glad I took the chance and bought this. I am a beginning again lap swimmer who has had spine and brain surgery. Turning my head brings on vertigo and nausea among other things. I also struggle with breathing. With this mask I am able to maintain a comfortable head position, I can breathe through both my nose and mouth as I need to. The shape of the mask allows great vision all the way around. I have yet to have a leak.it seats easily on my face and comfortably even across the top of my nose. The respiration is easy and expelled out both sides of the mask far enough back that bubbles never get in the way of your vision. I worried a little about CO2 but have had absolutely no problem. The ball in the snorkel is great. I don't miss having to clear it. In open water it would be a blessing for sure. The straps at the back are super comfortable and easily adjustable. I can pull my hair back and not have it sit on pressure points all at once. I especially like the snorkel being centered, it's easy to always make sure I know where it is. It also sits at a great angle when I stand up in deep water so it isn't easily accidentally submerged. If you need to breathe through both nose and mouth and want all around comfort I recommend this one highly.
