SealLine MAC Sack
Here's what other sites are saying:
Protect your gear from the worst with the MAC Sack, SealLine's Marine Compression Stuff Sack constructed with PU-coated Oxford nylon. Designed with the input of the US Marine Corps, this bag has easy to pack, the flexible, low-profile purge valves that stay out of the way for snag-free packing and the shell material is not only burly, but ultralightweight.

Like its larger sibling the SealLIne ILBE Sack, the SealLIne 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.
