Hinged vs hingeless

I recently bought a pair of hingeless sunglasses. While it's nice not to have to worry about the hinges breaking or getting loose, I never realized how convenient it was to have them there. Used to hang them from my shirt collar, or a strap on my backpack. Now I have to carry them in one hand, since the titanium frames don't let me hang them anymore. Guess I could wear them on my head, but the frames aren't really long enough to be effective that way. Just something to keep in mind when deciding on hinges or no. Nevertheless, these are great sunglasses.
