Wait, so just to be clear....we are under the assumption that Cressi makes equipment that can be called scuba gear
And do you know what's funny, I finally "fixed" my Hollis M1. It would always drive me nuts how I could never get a good seal on the mask.
My Brute started acting up with the nose leaking (the same as the M1) and nothing I did could fix it. After the 3rd week it finally dawned on me what was happening. I had been working from home and shaving every Monday, but leaving it for the rest of the week. I don't grow a lot of facial hair--shaving every 3-4 days keeps me "work acceptable", but me leaving it for a full 5 days and diving on the weekends without a single shave was enough to cause the leak. While the Brute might take 5 days of hair growing to cause a leak, the M1 has a "weaker seal" and only requires 3 days of not shaving to cause a leak. Did a fresh shave and dove the M1 all weekend, no issues whatsoever.
It just goes to show you have the littlest change is routine can cause (and in this case fix) problems.
