The Zanheadgear Flydanna is a bandanna that has been sectioned into 6 panels and transformed into a headwrap. By keeping sweat from a rider's eyes and preventing sweat and skin oils from soiling helmet liners, the Flydanna works well as a moisture barrier underneath a helmet. Additionally, the Flydanna keeps hair from getting snagged on earrings or tangled in the wind. 100% cotton. One size fits most.
