The 5SDB Bald-Head Protector™ allows you to protect your dome from the sun (head peel is a real thing) in the summer and in the winter you can use it like a warming full head cover-up Ninja-type thing. It’s way more badass than a hat, plus it’ll keep the sweat out of your eyes while drinking, and is hand washable so it won’t stink. If you have hair, they work great for you too, and are Unisexy.
