XL SNORKEL MASK SKIRT!?

You just answered your own question. Hit a dive shop and start trying them. Every manufacturer has different fitting masks. One person's large face is not the same as the next person with a large face. The only way you're going to find "your" mask is to try as many on as you can and whittle down your fits.

A good test to do in the dive shop is this:

Without putting the head strap on, place the mask against your face and inhale a little through your nose, mouth closed. Stop the inhale, take your hands away from the mask. If it stays put for 30 seconds or more, it's a good fit. Put that mask aside as a possible purchase. If it doesn't stay on, then put that mask in the discard pile.

Once you have some choices in the "keeper" pile, start narrowing down your choices remaining by fit, visibility and finally style and colour.

You should have at least one or two masks remaining in the "keeper" pile to choose from.

Edit: I get small floods too when a buddy does something silly enough to get a laugh or smile. Sorry, but other than to keep on trying them (beg borrow or steal a couple that test well in the shop), you're still back to the old "everyone's face is different" thing.

Also, it takes a little time for a new mask to conform to your face. It took me a couple of weeks to have mine fit comfortably. It is a little harder for me because I am asian, and I have a flatter face and high cheek bones.
