The Flydanna is a bandana, cut into 6 panels and sewn into a headwrap with a tail and ties at the nape of the neck. It is designed to sit securely on the head using the attached ties, allowing one size to fit all. Flydannas are great under a helmet as a moisture barrier. They help to isolate grease and sweat from the helmet liners and sweat from falling into a riders eyes. The Flydanna protects hair from getting snagged on earrings and from becoming tangled in the wind. Flydannas are created specifically for the biker with unique, bright and colorful graphics made to be seen at long distances. Made from 100% cotton. One size fits most.
