sorry if it's already been asked but i'm curious, i'm out and about alot and haven't seen one person wearing one, was on the isle of wight recently for 2 weeks and didn't see any there either.
anyone using them and how many do you use a day ? also do you feel more confident wearing them that it might help ?
yabu i'm using them, it's the sensible thing to do
yanbu not using for my own reasons
