Do You Wear A Cap Underneath Your Bicycle Helmet?

I have a Giro helmet, known for their extra large sizes. I often wear a soft visored cap (no buttons on the top) to keep the setting sun out of my eyes later in the day, While I have never fallen on it, I suppose I should get a new helmet soon,
Cycling caps traditionally have no top button (like a cricket cap?) and are lightweight cotton or wool in winter that fit snugly under pretty much all helmets unless mtb full or half face etc.
 
I've worn a cap under my helmet only if I plan to wear a hat when I'm off the bike at my destination. Other then that, just the helmet.
I guess I'm the opposite, i wear cycling caps most rides, but not when off the bike! I don't have the long skinny face for it, mine's too round and it looks like a child's cap perched on my head! I wear all kinds of other caps and hats off the bike. Wearing an old straw hat at the moment as we have a massive heat wave.
 
Daughter just happened to get me an Outdoor Research Swift Air cap for Fathers Day.

Weighs nothing, soft bill, no top button, ventilated all around head. Would seem ideal for under-helmet use per this thread, but I don't like the way my Specialized Chamonix 3 helmet fits over it and doubt I'll use it this way.

For one thing, I only get an extra inch or so of bill beyond the helmet's visor. Probably somewhat helpful in low sun, but not enough for me to take the safety risk.
 
I just saw this thread for the first time this morning…

I wear two different caps under my helmets:

1. Headsweats cap, without brim, for colder weather riding under my road and MTB helmets.

2. Because I like the sun blocking benefit of the visor on my Fox Speedframe Pro MTB helmet, I picked us some Arcweg Cycling Caps, with a brim, to wear under my Giro road helmet. Though brim is tiny compared to the Fox MTB helmet, though yesterday, I wore this cap backwards, as I sweat a bit. It cover the forehead between my glasses and lower edge of the road helmet.

The extra benefit of the small brimmed caps is BEE DEFLECTION!…Twice, last year, I had bees get stuck behind my glasses, on the same road I ride often (for about 15 years). This was without wearing the cap.

Since these were both mentioned above… I added Cat-Ears AirStreamz wind blockers to my road helmet. They do help a little - it’s difficult to quantify. The aforementioned road, is mostly open on both sides, in a very windy area. So it often drowns out anything I am listening to. I wear SHOKZ OpenRun Pro 2 headphones. They are great of light background music or podcast, and sound alerts from my Varia radar. I still hear the rocks below my tires, and various bike sounds when wearing the headphones since they do not cover your ear canal, and only listen at low to medium levels.

I should add that this would be an excellent hat to fold up and carry in a pocket for head and eye shading during stops. However, a little pricey at $36.

When safe, I also use the OpenRun for music on the bike. (I like to pedal in time with music carefully curated for that purpose, including my preferred cadence.)

Another good use is taking important calls (not texts) in the saddle from a phone tucked safely away in a pocket. One button press on headset to answer, another to hang up.

It pains some people to have to call instead of text. But hey, life is hard.
