This is a genuine US Army surplus 5-piece Improved Modular Sleep System (IMSS), made in the USA by Tennier Industries. Each sleeping bag system contains 5 components, described in detail below: the patrol sleeping, the intermediate cold weather sleeping bag, the bivy cover, and 2 compression stuff sacks. The sleeping bags can be used independently or snapped together into the sleep system, providing comfortable year-round sleeping conditions. Snaps hold the sleeping bags and bivy cover in place, so they will not move or slide around on you when you're trying to get in or out. Together, the sleep system is rated down to -30° F or -40° F.

We receive these items in bulk from the military and most are in great condition, with some appearing to be like new.  Use the quality guide below to see descriptions of each condition available.  The pictures featured here are stock photos and not of the actual item you will receive, but the actual item is of similar condition and quality. The dimensions of the different components are listed below, and should be considered rough estimations.

Quality Guide

  • Like New - A sleeping bag that appears flawless and never issued or used.  We receive these items in bulk from the military so we cannot say for sure whether or not they are brand new.
  • Excellent - The bivy covers will be crisp and appear to be in the "like new" condition.  The other sleeping bags will be in "very good" condition as described below.
  • Very Good - A sleeping bag that shows very minor signs of use but is in great condition.  No holes, rips, or tears in any of the components.  All zippers, snaps, and drawstrings will function normally.
  • Acceptable - A sleeping bag that will show signs of moderate to heavy use.  Any defects will not hinder the sleeping bag's intended use and would be easy for someone to repair.  There may be one or more small holes in the fabric (most are pin-holes but some may be larger, up to approximately the size of a dime).  All zippers, snaps, and drawstrings will function normally. 

Included Components

Patrol Sleeping Bag - Foliage in color, this mummy-style sleeping bag is rated for temperatures down to 30° F. It features an oversized zipper for easy opening and closing, and snaps for connecting to the other sleep system components. It also features a draft flap over the zipper to prevent heat loss, as well as a drawstring cord around around the hood to seal in even more heat.

Intermediate Cold Weather Sleeping Bag - Urban grey in color, this mummy-style sleeping bag is rated for temperatures down to -10° F. It features an oversized zipper for easy opening and closing, and snaps for connecting to the other sleep system components. It also features a draft flap over the zipper to prevent heat loss, as well as a drawstring cord around the hood to seal in even more heat.

  • Width, at feet: 23"
  • Width, at shoulders: 35"

Bivy Cover - The bivy cover is dark grey on the bottom and has an ACU camouflage pattern on the top. It is made with a 3-layer GORE-TEX fabric, making it fully waterproof. It has a zippered closure with snaps for connecting to the other sleep system components. It also features Velcro fasteners around the hood which can be fastened to prevent openings during rainy or extremely cold weather.

Compression Stuff Sacks - The Improved Modular Sleep System comes with a large and a small compression stuff sack, both grey in color.

Comfy Hoodie
Size: Large, Color: Mg03- Splatter1
This brand makes some decent stuff. This is a nice thinner hoodie with some stretchy materials and a cool splatter design. Comfy and easy to move in/ use for active occasions or just for chillin. Very versatile. Color doesn’t fade or hasn’t yet for me and I like the contrasting drawstrings. Size is right on; I ordered a size up and there’s plenty of room for layering. However if you put anything heavy in the front pocket, like a wallet, the material will give way and sag.

Buy it.
Size: Large, Color: Mg03- Ethnic
I dont leave many reviews, because life. However, this pullover deserves a review. Yes, it is big. Normally I would wear an XL but ordered a L based off sizing and reviews. The L is a hair big but I love the way it fits and its comfy.bthe color and quality is great. It is a little warm with the fleece lining, so it will be worn inside until fall, ir on cool summer evenings. I bought 2 and may buy more.

Big guy, big smiles!
Size: XX-Large, Color: Mg03- Ethnic
I picked two different patters of these lightweight hoodies for golfing and they're now an everyday item! Active wise, these stretch in every direction while moving without friction. I wore this hoodie for the first seven holes before the sun broke through the clouds without noticing it. My only concern, while premature is the stiching on the sleeves. I felt the loops catching the velcro on my glove a few times, but after 7 holes, and 20+ shots, I didn't see any sign of abrasion. I'm a big guy, 6'4" 290# I usually wear a XLT shirt and picked these up as XXL. Wasn't swimming in them, they fit nicely and fell in line with the hem of my shirt. I plan to buy several more!
