I use a baseball-style cap (a plain one, I dislike logos) in summer. In winter, an insulated/waterproof hat with a peak and earflaps keeps sun out and warmth in - like this one from Lowe Alpine:

I reckon sunvisors would simply be in the way when folded down. OTOH if folded up they could be useful wind deflectors! Flat caps, not my cup of tea at all.
