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. If you're going down into colder and colder temperatures, the Intermediate bag is the first thing you'll want to bring out.

Manufactured in the US by Tennier Industries (as with the rest of the MSS) the Intermediate bag is the warmer and denser bag in the MSS. When paired with the Patrol bag, can go down to some seriously cold temperatures (sub -10°F). And with a user wearing various layers of the ECW system and combining with other pieces of the MSS, is rated down to a staggering -50°F! 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, 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.

This configuration will protect from -10°F to -50°F when used with the layers of the extended cold weather clothing system (ECWCS)

  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

Great cold weather bag

I know the official Army guide says 30 and below; but I break this out if it's getting anywhere below 50. I like to be comfy. That said this bag alone will absolutely take you down to about 10 F and you'll still be nice and warm if you wear your silkies inside. Anything below that though and I recommend snapping this inside the patrol bag and using them both.
