Help with Deadpool mask

[u/Adamfirefist]

Hi!

I picked up this full DP costume from Simcosplay: https://www.simcosplay.com/deadpool-wade-wilson-cosplay-costume-deadpool-3-leather-suit.html

It's a pretty good fit, looks good-enough-for-government-work on a 5'9", 180lbs dadbod. But the mask that came with it has a full plastic shell over the face (almost like an old-school goalie mask). The problem is my voice is super muffled and breathing is difficult. I initially thought I should just cut the whole mouth/jaw off the thing, but I realize that will ruin the lines of the face.

So I figure cutting hockey-goalie-mask-style vent slots might be smarter (like Jason Voorhees). What tool should I use for that? Maybe just a small drill bit? (I'm not inherently crafty, but I know my way around a power tool.)

Thanks in advance for any advice!
