  • Features

    • 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. (10.7 L) 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 not included) 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.
