The 10-liter Ursack Major bear sack is made of bulletproof Spectra fabric that's designed to prevent bears from getting your food while you're backpacking and camping.


  • 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
