Military Sleeping Bag Compression Stuff Sack - Black - 9 Strap
This is the compression stuff sack designed for the US Military Modular Sleep system.  These are made by the same US Government Subcontractor that makes the ones sold to the US Military, and are made from the same grade of materials, to the same specifications.  These ones do NOT have the US Military label on them, but are otherwise identical and come out of the same factory.
