The camouflaged MAG Pouch is a piece of stealth technology used by S.H.I.E.L.D. for the purposes of access and infiltration.
During their mission to infiltrate the facility where South Ossetian separatists built the Overkill Device, Agents Grant Ward and Leo Fitz used a MAG Pouch to adhere to the underside of a truck and enter the compound.
The MAG Pouch is a sleeping bag style pouch that holds two men. It is made of a magnetic fabric that mimics its surroundings making those hidden inside virtually undetectable.
Agents using the MAG pouch position themselves in the middle of a road and wait for a passing truck. Once the pouch is zipped, it is undetectable and magnetizes to the bottom of the truck as it passes, allowing the agents access to the truck's destination.
