The headband also includes a second end section having a fastener attached adjacent the end thereof. The fastener includes a flexible lever arm and a cooperating connector biased in an engagement position with at least one of the plurality of connectors of the first end section to hold the headband in a selected loop configuration. The flexible lever arm is movable to a release position upon application of force thereto to cause the cooperating connector to disengage from the at least one the plurality of connectors of the first end section to enable increasing the size of the loop of the headband. The plurality of connectors of the first end section can, for example, be ratchet teeth.
