Bests & Worsts Reviews from Amazon

I purchased a "backpacking" mummy bag that did not come with any means of storage or transport. I bought the Granite Gear Round Rock Solid Compression Sack to stuff the 10* sleeping bag to a packable size. I would like to thank "Concerned Consumer" for providing some dimensions for the different sized sacks, I would also like to add some more information found on the product package to help others determine the proper size needed.
