The Flydanna® is a bandanna, 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. Flydanna®s are great under a helmet as a moisture barrier as they help to isolate grease and sweat from helmet liners. Unique and colorful designs. Tail protects neck from the sun. 100% cotton. One size fits most.
