I use a Mares Lirica as my primary mask. It leaks, a lot, as do all my others when I do nothing. Depending on how many dives I am planning I may just goo up the mustache with a little silicone grease which helps, but I still get a little leakage. If I will be doing multiple dives over multiple days, I trim it a bit below the nose, add a dollop of silicone and no more leaking mask.
