Marine Corps Stuff Sack

After Action Reports from Operations Iraqi Freedom and Enduring Freedom demonstrated a compelling need to provide a waterproof bag to protect personal gear from the elements, rain, sand, snow, and moisture. The Marine Corps Stuff (MACS) Sack will provide Marines a better method of waterproofing and sorting their personal gear stored inside the ILBE packs.
