I've been known to use the collapsible rubber hoods.

AMEN to that. Not elegant, not handsome, not OME. BUT, inexpensive; easily collapsed on the lens; easily stored in a camera bag where they will not scratch or be scratched by other equipment; cushions the front of the lens; do not get shiny spots around the outer edge as metal hoods do; if they get dirty they can be washed (!); AND FINALLY: 100% effective = do everything they are supposed to every bit as well as hoods that cost five times more.

Disadvantages: not as good on a zoom lens, which are better served by a tulip hood. Replacing the latter with a rubber hood means getting one for the shortest FL of the zoom.

WHAT I DON'T LIKE about rubber hoods: they are all screw-on, never bayonet, and never the obvious design, pinch-click to mount like a lens cap, and yes, this is possible for a lens hood or a filter.
