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.
