The Rampart® Chemical Biological Defense Overgarment is a two-piece system comprised of a coat and trousers designed to be worn as a duty uniform by tactical users, including Special Weapons Assault Teams (SWAT) and First Responders.

Originally designed for the U.S. Department of Energy SWAT, the coat and trousers are more form-fitting than the U.S. Department of Defense JSLIST garment. The Rampart Overgarment is comprised of GENTEX's Lifetex® CD-2560-4 fabric, which includes an outer layer of 50% cotton/50% nylon woven ripstop fabric with a durable oil and water resistant finish.

The overgarment system has been member tested and member approved by tactical users, such as the National Tactical Officers Organization (NTOA). The system also meets performance requirements similar to those required in the JSLIST program. Overall, wearers are offered protection against chemical and biological agents in a system that is lightweight, launderable and permeable to provide the lowest possible level of heat stress for a system of its type.

The coat features a functional hood, which interfaces with several respirators, including the MSA-Millennium, M40, M50, M53 and MCU-2P. The coat is also specially tailored shorter than other tactical garments, preventing interference with the wearer's utility belt. The waistband and wrists feature Velcro® tabs for further fitting adjustments. Zippered pockets on the front chest area offer access and storage of essential tactical gear and accessories. The coat is first secured closed with a nylon zipper and then a Velcro® overflap.

The trousers feature a high bib-style waist, extra-wide, adjustable suspenders and zipper closures at the leg bottoms. Flapped pockets are featured at both hips for additional tactical gear and accessories.

The coat and trousers both feature additional fabric layers at the greater wear areas - elbows and ankles.

The standard color is solid navy. U.S. Woodland and Desert Camouflage, as well as other colors are available for the outer shell fabric. The Rampart Overgarment coat and trousers are packaged and sold separately. Sizes may be mixed and matched for each individual wearer.
