Just a FYI for those of you who wonder how seriously things like this are reviewed. I have no recollection of having been in my pool in October, ever! I was in this afternoon to test this mask and snorkel. The water temperature was in the 60 degree area. I suppose I could have fired up the heater but a couple of hundred dollars of propane to test this didn't make sense. Of course I had a family member suggest it made no sense being in the pool on October 1, regardless of my reasons.
I have never had a nicer mask or snorkel. It adjusted easily and the adjustments held. I have had cheaper masks that after a few minutes in the water the adjustments re-adjusted on their own. Ten laps in the pool and everything remained stable. I dove down and the valve on the snorkel closed as it claimed. I did a fair amount of kicking to increase turbulence to see if the valve on the snorkel let in water that way, it did not. I am not a professional diver so I don't know how this compares to professional grade gear but I was impressed with the quality and the functionality. I was not impressed with how darn cold my pool is in October in
