Not my picture, it is an anonymous forum after all, but I sport a flavor safor a la
even though I feel a full scale goatee like
would seal equally well since the mask would fit over the goatee rather then sit over a beard.
I have spoken with FAA Inspectors that are very adament that a mask will not seal and it's therefore a safety issue.

Personal opinion? I think the whole "does not seal" argument is BS.
