Joint Service Lightweight Integrated Suit Technology (JSLIST)
The Joint Service Lightweight Integrated Suit Technology (JSLIST) ensemble is a set of overgarments that provide protection against chemical and biological agents, radioactive fallout particles, and battlefield contaminants.
Joint Service Lightweight Integrated Suit Technology (JSLIST)
The Joint Service Lightweight Integrated Suit Technology (JSLIST) garment is used along with CB protective gloves, CB protective footwear, and a field protective mask to create a state-of-the-art chemical/biological protective ensemble that provides complete percutaneous and respiratory protection against CB warfare agents. JSLIST is an all-Service program that provides both vapor and liquid protection from the damaging effects of all known biological and chemical agents and radiological particles.
The JSLIST ensemble is specified for wear in MOPP 1 through MOPP 4 conditions. The JSLIST ensemble includes a blouse and trousers, supplemented by JSLIST protective footwear and gloves. The JSLIST ensemble is intended to be used with the Joint Service General Purpose Mask (JSGPM) or the M40 / M42 / MCU-2/P series masks for complete protection.
JSLIST replaces earlier protective systems including the Battledress Overgarment (BDO), the U.S. Navy Chemical Protective Overgarment (CPO), the Marine Corps Saratoga and other prior systems. JSLIST advantages include state-of-the-art protection, reduced heat stress, full compatibility with all interfacing equipment, longer wear, launderability, a single technical data package and technical data manual, a standard tariff, split issue to improve fit and reduce inventory, and flame retardancy.
Joint Service Lightweight Integrated Suit Technology (JSLIST) History
The Joint Service Lightweight Integrated Suit Technology (JSLIST) Program was defined in a 1993 Memorandum of Agreement by the four U.S. military services. A field study was conducted at Yuma Proving Ground, AZ in the summer of 1995, and a controlled environmental chamber study was conducted in the summer of 1996 at the United States Army Research Institute of Environmental Medicine and the United States Navy Clothing and Textile Research Facility, Natick, MA.
JSLIST production began in August 1997 with the coat and trousers. JSLIST boots and gloves were specified for later procurement. JSLIST suits were issued to Marines and Soldiers as stocks of older protective systems reached the end of their design lifetimes. Combat units in OEF and OIF employed the JSLIST ensemble. Hundreds of thousands of JSLIST ensembles were procured in the 2000 to 2005 timeframe while research continued on gloves, boots and other improvements.
Joint Service Lightweight Integrated Suit Technology (JSLIST) Components
The JSLIST components are available in 4-color Woodland or 3-color Desert Camouflage patterns and in the full range of military sizes (see JSLIST Size and NSN Charts). Alternative camouflage patterns for Special Operations Forces (SOF) are also available. The principal and alternate components of JSLIST are:
The Basis of Issue for JSLIST is two per Soldier, three per Marine.
Joint Service Lightweight Integrated Suit Technology (JSLIST) Description
The JSLIST waist-length coat has an integral hood, a zipper covered by a Velcro flap, enclosed extendable elastic drawcord hem with jacket retention cord, full-length sleeves with Velcro wrist closure adjustment tabs, and an outside expandable pocket with flap on the left sleeve.
The JSLIST trousers have expandable pockets, adjustable suspenders and adjustable waistband. They also have a front zipper opening with a protective flap, and a bellows pocket with flap located on each thigh. Each leg opening has Velcro ankle adjustment tabs.
The JSLIST coat and trousers' outer camouflage layer repels water and its inner layer is designed to provide the user with protection from the effects of chemical and biological contaminants and toxic industrial material in any form including anthrax, sarin gas and smallpox. The JSLIST garment's outer shell is 50/50 cotton/nylon poplin ripstop fabric with a durable water-repellent finish. The material is flexible and can breathe without losing any protection. The JSLIST liner consists of a non-woven front laminated to activated carbon spheres and bonded to a tricot knit back that absorbs chemical agents.
Depending on the temperature and mission, the JSLIST overgarment may be worn over the standard duty uniform, over underwear, or over / under cold weather garments.
The JSLIST suit weighs only 5.6 pounds, 15% lighter and 60% less bulky than its predecessors.
The Multipurpose Rain/Snow/CB Overboot (MULO) is made by injection molding an elastomer blend, compounded to provide the characteristic chemical and environmental protection required. It incorporates two quick-release side buckles and is designed to be worn over the standard issue combat boot, jungle boot, and intermediate cold/wet boot. The MULO provides 60 days of durability and 24 hours of protection against liquid chemical agents. The MULO is capable of being decontaminated to an operationally safe level using standard field decontaminates. Environmental protection is provided against water, snow and mud, in addition to petroleum, oil, and lubricant (POL) and flame resistance.
Joint Service Lightweight Integrated Suit Technology (JSLIST) Wear Limits
The protective qualities of the Joint Service Lightweight Integrated Suit Technology (JSLIST) ensemble depend on the impregnated chemicals, activated charcoal and the condition of the fabric in the suit's components. At the factory, JSLIST suits are vacuum-packed and heat-sealed in nylon foil. An outer plastic bag provides additional protection against exposure to harmful substances, but it is not airtight. A reusable, sealable plastic storage bag is packed with each item. The coat bag is folded in with the coat. The trouser bag is packed in the trouser cargo pocket. The JSLIST has a shelf life of five years if unopened.
The JSLIST can be worn in a contaminated environment for 24 hours. In addition, JSLIST users must keep track of how long the JSLIST suit has been out of its original packaging bag, and how many times it has been washed. The limit for wearing the suit is 45 days total and the limit for washing it is six times. Once the suit is taken out of its bag, it's good for a maximum of 120 days. After any of these limits have been reached, the JSLIST suit is good only for training. Such overlimit suits are turned in and FOR TRAINING ONLY is stenciled on the outer surface.
The JSLIST garment labels have boxes for keeping track of washings and usage. Users are trained to mark the label after each washing.
