If you tend to feel the cold, then a snug hat will help your body retain heat. Not only does it insulate, it will keep the constant warmth-removing breeze from the top of your noggin, and protect your ears to boot.
Functional windstopper skullcaps are designed to fit under a helmet easily. You can also get more stylish numbers that look good as well as performing a vital function. Peaked caps provide a bit of protection from sun glare and light rain, and there are toasty wool options if you want to go for all out warmth.
If you are out shopping for these, it’s worth trying them on with your helmet just to make sure they fit. Even the thinnest hat will make a noticeable different to the fit of your helmet, and you don’t want to be uncomfortable when you’re riding.
