Abstract: A wearable system for securing a device against a torso of a user. In one embodiment, the system includes an adjustable strap attached to a flap. A connector attached to opposite ends of the strap facilitates securing the device between the flap and a torso of a user via pressure applied by the strap. In a more specific embodiment, the device is an optical device, such as binoculars. In this embodiment, the flap is selectively attached to the strap, enabling the flap to exhibit an open configuration, a protective configuration, or a forward-folded configuration. When the flap is in the protective configuration, a section of the flap covers an aperture, such as a lens or other opening, of the optical device, thereby protecting the aperture. When the flap is in the forward configuration, a first portion of the flap is folded behind a portion of the elastic strap that extends between first and second connections that secure the strap to the flap.
