A fastener is coupled to the first strap portion for securing the end flap segment in the looped configuration. A buckle includes a buckle frame, a cross bar, and at least one tool bit. The buckle frame defines a longitudinal frame axis, and the cross bar extends between opposed portions of the buckle frame and defines cross bar axis that is generally perpendicular to the longitudinal frame axis. The tool bit is pivotally coupled to the cross bar and is pivotable about the cross bar axis. The tool bit is sized and positioned to be captured between the end flap segment and the body segment when the end flap segment is in the looped configuration.
