In the time of Covid, we will need to show our CDC card and possibly our passports at different times. I normally use a "hidden pocket" type moneybelt that hangs inside my pants leg. But that's not convenient to constantly get out and put back in. So, I bought a neck wallet big enough to hold both. Unfortuately, the shape of the thing can be seen under my clothes. (I wear mostly polo shirts.)
In today's day and age, protecting these two documents from loss or theft is a requirement. I'd like to get suggestions on what others are thinking of doing to both protect the documents but have them readily available. (Keep in mind, I'm a guy who doesn not carry a purse.) And I'm not a big fan of backpacks because you really can't see what's going on behind you.
