I've worn in public a few times here and there. In truth, I have worried how easily I'm spotted, but have ultimately learned that most people don't care. So long as nothing is blatantly out of place (bad leak, or diaper peeking out a great deal) nobody is going to give you a second glance. I've had a near-hit or two with the leak side, but have worked around it long enough to get home and clean up. For noise, I typically make use of a set of housekeys I wear on a belt loop of my pants. Their constant jingle is a distinctive enough sound to cover up any diaper rustling (it's so distinctive, in fact, that I am identifiable by it)
