Review on Outer Limits Full Face Snorkel Mask Adult - Enhanced Visibility and Breathability with Carrying Bag. Experience Unobstructed Panoramic Views and Easy Breathing. Longer Snorkel and GoPro Compatible Gear Included. by Mike Mitchell

It worked as advertised and definitely changed my diving experience. For some unknown reason, I decided to use the snorkeling mask provided on my tour, but I had some trouble breathing while managing my gear. I changed and used this mask and everything became easier. The seal around the face was airtight and the mask did not fog up. I found that I used to breathe through my mouth, but as I relaxed I was able to breathe through my nose. The water valve worked fine when a small amount of water got in, but that was rare. I liked the seamless viewing lens that made it easier to see my surroundings. When I ordered the mask I simply used their instructions and measured my face for the correct size. It was correct and while snorkeling the rubber pad was great! I would suggest taking the mask out of the packaging and letting it air out for a few days before use to get rid of the plastic smell - if you have a sensitive stomach this can be overwhelming when snorkeling. I would also suggest having a Jaws anti-fog spray. There are no perfect maximum values and it also depends on the water temperature. There are also magnetic wipers, but spray/baby shampoo/toothpaste is a must. If the padding doesn't seal perfectly—and you've measured your face to the exact right size—simply tighten the mask to keep it on your face. This can cause headaches and leave red marks, but will prevent water from leaking out. But I had no problems and didn't have to follow suit. I also saved the plastic wrap and padding to protect the lens surface from scratches - you want to keep that area sand-free, especially if you're packing in a bag that can scratch. In conclusion, I would argue that this mask creates lens distortion - it makes distant objects appear closer - it's similar to the effect of a dome lens on an underwater camera. This provides a clearer view, but alters your reality and takes some getting used to. I think this mask was great and really made my snorkeling experience easier.
