I finally got to dive my new liquidskin mask Sunday and Monday. On Sunday I wore it for 2 1/2 hours in the pool - it was dry and comfortable, but I was still reserving judgment since my mask problems usually don't show up until the third or fourth dive of the day. I have gone through lots of masks in my search for a mask that will stay dry for an entire day of diving - I have tried ScubaPro frameless, several Omer models, Akona, Cressi, Oceanic, Ocean Master, Halcyon, Mares X-Vision and X-vision mid, and more off brands than I can count. I had settled on using a Mares X-vision mid with an Omer Alien as a back-up - the Alien is actually a little drier, but I like the larger field of vision that the X-vision offers so when I heard about the new Liquidskin x-vision I was looking forward to trying it. It absolutely lived up to the advertising hype. I did 5 saltwater dives yesterday (total in-water time was probably 3 1/2 hours) and it was just as dry on the last one as on the first. It was also the most comfortable mask that I have worn. It was well worth the $90ish price tag if you are having leaking mask problems or fit problems. And yes, I can clear my mask with no trouble, I just hate wasting dive time doing it constantly.
YMMV,
Jackie

Yay!! But I do think it's funny that Dennis acts like this mask is new or something...I've had mine for months!!!!
