A suicide prevention vest or smock works by being made of tear-resistant, thick, and durable material that cannot be rolled, twisted, ripped, or folded into strips to form a noose or weapon for suicide attempts. These garments provide warmth and modesty while preventing individuals in hospitals, psychiatric institutions, prisons, or detention facilities from using the clothing itself to harm themselves. Adjustable straps ensure a proper, comfortable fit without obstructing movement, and the special quilted and layered fabric construction makes it impossible to tear or manipulate the garment into a harmful shape. This effectively prevents hanging or other self- harm methods that rely on fabric from the garment.
