The Ares Gear "Duty Belt, LE (Inner) is now available. Says Ares Gear, "Now we have a best as stiff as a Ranger Belt but with no buckle, so that it can be worn underneath a duty belt without the added bulk of the Cobra buckle."
Retailing for $49.99, the new Inner LE Duty Belt is made to be worn as an inner belt with a LEO type duty rig. It's made of 2 layers of 1.5" scuba webbing with hook or loop on the outside so it can be mated with a duty belt. It overlaps in front and is is secured with double straps of hook and loop.
Available from 28" to 44" waist. More at the Ares Gear website.
