Sought after for its fantastic performance and relatively low weight & profile, the US modular sleep system (MSS) has some of the best sleeping bag components money can buy. Here, we have the crown jewel of the whole thing - the versatile and comfortable Patrol Bag.

Manufactured in the US by Tennier Industries (as with the rest of the MSS) the patrol bag is the lower profile bag, and while not for weather at an extreme of -30° F, It's a jack of all trades for most climates (although it's not recommended for hotter climates). Constructed out of water-resistant, non-flammable ripstop nylon for virtually worry-free durability, and stuffed with Polarguard® HV hollow continuous filament resin-bonded polyester (say that 10 times fast). It features a heavy duty, self-repairing double zipper down the body that can be quickly undone in an emergency, a cinchable hood to aid trapping your body heat in the bag when it gets cold (don't tie the drawstrings though, it says explicitly not to do this right on the bag), and snaps to attach the other pieces of the MSS or be used in lieu of the zipper in a pinch.

As a part of the MSS, it's also very packable. Using the stuff sacks designed for the MSS, the entire 3-part system (bivy cover, intermediate bag, and patrol bag) can be compressed down to a roughly 1 cubic foot volume with ease.

Use and Care Instructions

In case you receive a bag with a tag that's hard to read or damaged, here is a transcript of the information printed on it:

Keep Bag Dry

1. The outside of the bag is water repellent and will protect against light moisture
   
2. Select the driest ground possible
3. Breathe through the face opening to prevent moisture from wetting the bag
4. If face is cold, reduce hood opening by pulling on drawstrings. DO NOT TIE DRAWSTRINGS
5. DO NOT wear damp clothing and AVOID sweating in the bag. if too warm, remove some clothing or open slide fastener for ventilation.
6. When practical, open the bag completely and air dry through the day.
7. Use sleeping pad or bivy cover to protect sleeping bag from ground moisture and dirt
8. When practical, wear clean, dry clothing in the bag

Keep Bag Clean

1. Wear sleeping bag hood drawn around head.
2. Brush clothing, boots, and socks before entering bag
3. Remove grease and other contaminants from bag by spot cleaning with damp cloth and soap
4. Do not smoke in bag, keep away from open flame 

Laundering (DO NOT DRY CLEAN, STARCH, OR BLEACH)

1. Turn the bag inside out and close all zippers before laundering.
2. The sleeping bag shall be field laundered using formula II of FM 42-414 Appendix E.
3. Launder in a standard commercial washing machine on delicate/gentle cycle and dry in a standard commercial dryer set on low temperature, tumble setting.
4. Wash at less than 90°F. Rinse in clear, cold water.

Configuration

1. Sleeping Bag, Patrol is designed for use down to 30°F
2. Sleeping bag, intermediate cold is designed for use between 30°F and -10°F
3. Join bags by placing the intermediate cold sleeping bag inside the patrol sleeping bag and affixing the two at all attachment points. Use only the patrol sleeping bag zipper to enter and exit. This configuration will protect from -10°F to -50°F when used with the layers of the extended cold weather clothing system (ECWCS)
4. Use the bivy cover for protection from rain, snow and wind.

Slide fastener operation

1. To close the bag, keep both sides of slide fastener close together before pulling thong on the slider
2. for EMERGENCY EXIT, grasp each side of the opening above the slider and spread apart quickly forcing the slider downward.
3. If chain separates below the slider, pull the slider beyond separation, then pull slider up to reclose chain.
4. If slide fastener fails, use the attaching mechanisms intended to join bags together
