I wear a beanie: one for the cooler weather and a summer one to protect from sun. The cool beanie works down to 20 degrees. The summer one also wicks perspiration. I happened to get mine at Nashbar.com, but they are available lots of place.

I like a headband

Also have a neck gaitor, this way I have the top off my head open for cooling then just put on or take off as needed

I use a helmet cover, covers the air vents and is also water proof.During the summer I also have a net which is made for helmets. Nothing like having a bee come in the vents when you're bald

Kayacking skullcap. They were out before anything was available for bicycles and cover your ears. A full balaclava for colder temperatures. I'm not completely bald but I prefer shaved anyway.

Where a hat under your helmet. There are hats made for this purpose.

The thing about an under-the-helmet head covering, whichever of the many good suggestions you choose to run with, is that it is a much greater effort to change it mid-ride if you find out you didn't dial in perfectly from the start.

For that reason, I'm a huge fan of the helmet cover, which is super easy to whip off mid ride (albeit a bit more of an effort to put back on).

Once it goes below about 50, I almost always leave the house wearing one. If / when I take it off varies. If it is very cold, I might wear a skull cap under the helmet and still throw on the helmet cover over. More flexible to have the two layers, one of which is easily tweaked.

I absolutely love my Halo skull cap. Warm enough to use when cold. Breathes really well. Nice and stretchy. Sweat block technology works great for keeping the sweat out of your eyes.



If the Halo is dirty, I use a Buff. But the Halo works much better.

Adam and I have the same barber and for good parts of the year I keep the head shaved down to a #1.

Winter warrants a toque and as they are handy and free, use a welding beanie works well in the summer to keep me from getting sunburned through my helmet vents.

You don't have to be bald to experience the wrath of the bee. A couple of years ago, riding into work a wasp/yellow jacket got into one of my vents and proceeded to jack-hammer the bejeezers out of my head. I wasn't sure whether or not I should stop and go home or keep going. I kept going. The company safety officer's office was just across the hall from mine and when I got to work I told him what happened and asked him to check in on me from time to time in case I was lying on the floor.

I like using Under Armour mesh skull caps. Warm when it is a little chilly and they keep the sweat out of your eyes when it is hot. They work well under a helmet.

The kind of weather you describe can be handled quite well by a Halo doo rag.

Classic cycling cap. Cotton ones are cheap and fun to collect. A nice wool (Walz) are great in the winter.

I decided to grow some hair for the Winter, but I got annoyed with it after a couple of weeks and cut it again. Once you get used to no hair, it's difficult to go back to normal length hair. So I bought some extra caps and hats, and sometimes even wear one at work.

Had a skull cap but lost it. Now I just use the hood of my bike jacket under my helmet. Works fine.

I have a custom cap from Octopus Caps ( a local company, great stuff) custom made from a Futball scarf and wool. I use that until it gets below freezing, then switch to the balaclava. Anything above 45 and I let the skull vent, but I like it cold

There are Ski helmets ... Gyro, Bern and others make them, now,
2nd helmet for the cool season.. warm ears and head.

Bern even makes ones with a Carbon -fiber, thin and lighter, shell

Just discovered that Walz makes cycling caps of performance fabrics, and bought a couple of those. These'll be replacing my Underarmour skullcaps.

I have one of the carbon fiber Bern cycling helmets. It is really carbon fiber laminated onto thermoplastic -- so half carbon. Still, the smaller vents keeps it warmer when its cold out.

I use a bandana under the helmet

I have darker colors for colder weather and lighter colors for hotter.
Also have different designs depending on my mood that day . .

You will also have skin cancer by the time you are 60 -

Nice thing about being bald...



No helmet Hair...

Hmm. Bald guys asks about keeping his head warm. Hmm. You are putting us on, right? I mean, you've heard about things you put on your head, right?

Oh well, in case you're serious: I'm bald and have been wearing a cashmere cap this winter and love it.

+ 1 for Halo. I rock the Halo II headband on my shaved dome. Not for warmth obviously, but perfect for sweat.
