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.

Exterior Dimensions, when laid flat:

  • Length: 92"
  • Width, at feet: 24"

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.

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.

Works well when properly applied
Size: 3 Fl Oz (Pack of 1)
I try to always buy the highest SPF that I can find. This one fits the bill. If you apply it thoroughly all over and then reapply every few hours, you shouldn't get burned. I've worn it to the water park numerous times now. I have very sensitive skin, and it's given me no issues. I even put it on my face, just being careful not to get too close to my eye area. Once it absorbs into your skin, it doesn't feel too sticky like some other sunscreens can. Just be aware that it will leave a white residue on your bathing suit if you get it on there, but I've always been able to wash it out and that's a small price to pay for proper sun protection!

Very good... with a comment.
Size: 3 Fl Oz (Pack of 1)
As a bald dude, I fine the fact that it is matt good. Check it before you leave or, if you use to much, looks like white face upon drydown and in dry areas. I like it. I do. And it protected me from the hot sun of the middle east. No burn. Just needs a second check after about 10 minutes. But very good at what it does!!!

Excellent product.
Size: 3 Fl Oz (Pack of 1)
Excellent product. The sun is extremely strong where I live, and I've been using this for several days now; it lasts a very long time on the skin. However, if you have very sensitive skin, I wouldn't recommend using it on your face—in my case, it caused a breakout. But for the neck, body, and arms, it’s excellent. I highly recommend it, and it doesn't leave a bad feel on the skin or an unpleasant smell. If you use it in the water, it is recommended to reapply every hour and 20 minutes, otherwise you might get sunburned.

Daily Staple Sunscreen
Size: 3 Fl Oz (Pack of 1)
I’ve been really impressed with this sunscreen—it’s become a daily staple for my face and hands. The SPF 70 gives great peace of mind, especially with regular sun exposure, and it feels lightweight rather than heavy or greasy. It absorbs quickly and doesn’t leave that thick white cast, which is a huge plus for everyday wear. On my face, it layers well under makeup without pilling, and on my hands, it doesn’t feel sticky or transfer onto everything I touch. I also appreciate that it holds up well throughout the day without needing constant reapplication (unless I’m outside a lot). Overall, it’s a reliable, high-protection sunscreen that’s comfortable enough to use every day.

Best sunscreen
Size: 3 Fl Oz (Pack of 1)
My favorite sunscreen. Been buying if for 2 years and still a great product. It goes on easily and does not make your skin greasy or sweaty. It does not cause breakouts either.
