Okay just when I thought all was fine with a Non-schengen to Non-schengen transit at FRA, I note the following from the LH website:

Face Masks:

German authorities allow passengers only to wear the following

face masks:

• surgical masks
• FFP2 masks (without valve).
• N95 or KN95 masks (without walve)

Fabric masks are not permitted.
I wear a "fabric" face mask all the time in the U.S. Does this mean I have to purchase a mask compliant with the above noted rules to transit Germany? N95's are notoriously uncomfortable and I am fully vaccinated. I really hope my routine masks are okay.
