I wear mine all the time, don't even think about it and also gives a place to mount one of those small mirrors so I can tell what color car is trying to run me over. I've mentioned this before on here- one problem I have with my Giro helmet with all those fancy vents is that I was getting a really funny sunburn on my head due to my thinning hair (hey, I'm 63 so it's OK). Now when it's sunny out I put on a do-rag before my helmet. It makes it fit a bit snugger and a little hotter, but better than having my family laugh at my sunburned spots on my head.
