The system shall consist of two “Mumy- bag“ type sleeping bags (patrol bag and intermediate cold weather bag), constructed of water-resistent, ripstop nylon, a
6、nd a compression stuff sack into which the bags shall be placed. The patrol bag shall be designed for use in temperate climates (approximately 30 to 50 degrees Fahrenheit). The intermediate cold weather bag shall be designed for use in cold weather climates (approximately 30 to minus 10 degrees Fahr
7、enheit). The patrol and intermediate bags shall be fully functional indepen- dent sleeping bags. They shall be used separately, or together, by inserting the intermediate cold weather bag within the patrol bag, attached by using snap fasteners, to form an extreme cold weather bag system. The extreme
8、 cold weather bag configuration shall provide insulation to at least minus 30 degrees Fahrenheit for a user dressed in polypropylene expedition weight undershirt and drawers and standard cushion sole socks and to minus 50 degrees Fahrenheit for a user wearing various layers of ECW clothing. The maxi
9、mum gross weight of the combined intermediate and patrol bags shall be 7.0 pounds. The stuff sack, when packed with the sleeping bags, shall be capable of being compressed to one cubic foot and shall fit in the sleeping bag compartment of the large field pack with internal frame (MIL-F-44324). Each
10、bag, either independently or when joined together, shall be compatible with the vapor permeable bivy cover (MIL-C-44307). 3.2 Modular sleepinu bau components 3.2.1 Sleepinq baq, p atrol (type I). The patrol bag shall provide the user with adequate insulation to as low as 30 degrees Fahrenheit and sh
11、all weigh approximately 3 pounds. The insulating material shall be a lightweight, highly compressible, synthetic material conforming to requirements indicated in 3.3. The insulation shall not migrate in the bag. The patrol bag shall be found to be free from cold spots and no individual Clo value rea
12、ding shall be less than 5.5 when tested in accordance with ASTM-F 1291. Inside dimensions of the patrol bag shall be 90 to 92 inches, measured from the bottom of the foot to the top of the hood, 36 to 37 inches wide at its widest point, 22 to 24 inches wide at its narrowest point (measured across se
13、am at top footbox), as measured from side seam to side seam. Measurements shall be taken with the sleeping bag turned inside out. The foot section shall have an anatomically designed foot box and shall contain at least the same amount of insulation as the rest of the patrol bag. 2 I Licensed by Info

The slide fastener area shall have a draft flap or tube to prevent heat loss and shall be constructed to prevent the slide fastener from ina
16、dvertently catching the liner or draft tube or flap material. The draft tube of the patrol bag shall be constructed to lay against the slide fastener of the patrol bag inside the bag. The patrol bag shall have an adjustable hood for heat retention. The hood shall contain, at a minimum, the same leve
17、l of insulation as the rest of the bag. Adjustments to the hood shall be made by a cord and barrel lock. 3.2.2 Sleepinq Bas, Intermediate Cold Weather (ICW) (type III. The intermediate bag shall provide the user with adequate insulation to as low as O degrees Fahrenheit and shall weigh approximately
18、 4 pounds. The insulation material shall be a lightweight, highly compressible, synthetic material conforming to requirements indicated in 3.3. The insulation shall not migrate in the bag. The intermediate cold weather bag shall be found to be free from cold spots and no individual Clo value reading
19、 shall be less than 6.5 when tested in accordance with ASTM-F 1291. The foot section shall have an anatomically designed foot box and shall contain at least twice the amount of insulation as the rest of the bag. A chest collar shall be sewn along the inside of the intermediate cold weather sleeping
20、bag, at the top of the chest area, to prevent air- drafting up and down through the hood.
