Modular Sleep System (Improved / ACU)

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.
