why do people wear cycling caps under their helmets?

[Hacienda71]

Talking of which, are big noses aerodynamic?

They will help you win the photo finish by a nose

Yes!

And bald heads are hairodynamic……

It's a shame my beard counters that effect.

I have one lid with a visor, and one ( the same design ) I use without a visor ( if the weather is gash ) I ride with a cotton cycle cap under the visorless one, to absorb sweat, and shield from any sun that comes out:

I've had skin cancer - I like to keep the sun off and the sun cream just ends up cacking everything up.

For me personally, I wear a cap under my helmet for the simple reason of being a baldy it’s keeps the sweat out my eyes.

Stop sweat, stops sunburn, keeps rain of your face, keeps you warm.

My scalp became itchy while I was in France, enjoying not just the big Alpine climbs, but the European heatwave. It took a while before I realised why: I'd become sunburned on the scalp, because just before leaving Australia, I'd had my hair cut fairly short for a summer style, and so the sun was getting through to the scalp.

I don't like a cap on higher intensity rides but on slower rides I like the extra heat, they give, the extra protection from the weather, avoiding helmet hair and the ability the peak has to block out lights (sun light/ car lights).

The answer to the OPs question is obvious, especially in today’s weather - to stop them blowing off!
