A very rough rule of thumb is that if packed efficiently, the Ursack Major can hold about 5 days worth of food for 1 person Bag measures about 8 x 14 in. (diam. x H) when cinched closed, holds about 650 cu. in. and weighs 7.8 oz. Comes with an integrated 6 ft. long piece of 2,500 lb. tensile-strength cord Ursack highly recommends using an OPSak odor barrier bag or an aluminum liner (both sold separately) with the bag Updated version features a tighter weave and more than double the tear-strength of previous models Passed the Interagency Grizzly Bear Committee (IGBC) test and was placed on its bear-resistant products list on July 31, 2014 The IGBC list is relied on by many wilderness agencies but not all; wilderness restrictions may still apply depending on where you travel-please check first Made in USA.

This is a must when backpacking. I have both a canister and Ursack. The Ursack is definitely easier to pack. Make sure to have the liner as well. There are times I have to bring my beer vault but overall I prefer bringing my Ursack when possible.
