First: I am an Advanced Open Water Scuba Diver. I have several low-volume masks. At first, took this mask to my community pool (Olympic Size) to Combat Swim (underwater modified side stroke) 40 laps (80 lengths). I swim this way every morning, take a rest on Sunday. I have a normal face. Had a tiny leak on lap one. Turned out to be a little frontal hair that was trapped under the skirt. Corrected that, and continued for the next hour. Lots of twisting and turning while underwater, absolutely dry, no leaks at all. Good view, easy to adjust and super comfortable. My tip: Scrub the inside lens with WHITE toothpaste, not GEL. SCRUB THE INSIDE LENS with old toothbrush UNTIL GLASS SQUEAKS, then before diving, use saliva, rub it in, rinse with fresh or salt water. Crystal clear vision, no fog at all guaranteed. I see too many claim they used toothpaste and still their mask fogged. I have also seen incorrect application of the correct toothpaste and bad results. No need for antifog stuff. I have never used any antifog stuff, only WHITE TOOTHPASTE. Here is another tip: Order your mask now, because, as soon as the company finds out these masks are equal to the higher priced ones I posess..........? P.S. There are not that many in stock. I ordered another one, just now. UPDATE DEC 2, 2022----I started using this mask on a daily basis since it's delivery on Sep. 29, 2022. No matter how I twist and turn while combat swimming in the community Olympic Lap Pool, doing 40 laps (80 lengths) this gem of a mask will not leak. You do not have to strap it on tight to assure a good seal. It is extremely comfortable and, has a very good field of vision. I have other models of free dive masks and they do well, but sometimes ya gotta fidget with the strap to get a good seal. Not this mask. The skirt and the head trap design are pretty superior for a mask that cost a fraction of what I paid for my other masks. Just remember to scrub the inside lens real good with plain white toothpaste (not the gel) until you hear it squeaking, then rinse it real good, and apply saliva and rub and rinse before you swim. So, far, I have only scrubbed it with toothpaste, once and it still remains fog free. If you don't use any mask for a week, you will have to scrub the silicone off the lens. Don't be afraid to scrub hard. The lens are tempered glass and will not scratch. I hope this update helps you all.
