Like its larger sibling the ILBE Sack, the MAC Sack is a special-issue compression dry sack designed exclusively for the U.S. Marine Corps. It's the ideal solution for low-capacity, low-profile watertight protection in extremely abusive environments. It's made to order for year-round guiding, daily abuse and for those who are particularly harsh of their gear. PVC-Free. Color: Olive Green.

UPDATE: Cool thing but I would definitely like to have a bigger one. I didn't tested it under wet conditions but it looks like it should be just fine. Great for carrying documents, extra matches, cellphone, camera or other not too bulky water sensitive stuff.
