YOU DON’T NEED A MOGUARD.
A wet ‘stache is definitely not the worst thing in the world. Just wipe it off! Use a napkin, or your shirt if you have to, or just let your ‘stache stay wet. Is that so bad?
ON THE OTHER HAND…
if you really love your ‘stache and prefer keeping it perfect & dry, well, then the MoGuard might be for you.
