US Patent 7350241 Quick adjustment bandana device

A bandana device for use by a vehicle rider wearing a helmet, to protect against dust impingement on the face, whereby when the bandana is applied to the wearer's face and the corners are brought together at the rear of the wearer's neck and below the lowermost rear edge of the helmet, the components are then positioned to be pressed together to retain the bandana tensioned over the wearer's face, and to exclude entrance of dust and dirt beneath the bandana.
