As a guy with a big beard, 3M micropore tape works fine. Don't use the chin strap, tape is better at conditioning you to keep your mouth closed. The trick is to just use a shit ton of it. I use one vertical over lips then 4 other pieces for each corner that covers part of my cheeks where there is no hair.
