The perfect option for larger groups or longer trips, the 30-liter Ursack Major bear sack is a lightweight, collapsible and robust alternative to hard-sided canisters that fits easily in your pack.


  • A very rough rule of thumb is that if packed efficiently, the Ursack Major 30-liter bear sack can hold about 14 days worth of food for 1 person
  • Made from "bulletproof" fabric, it's lightweight, collapsible and bear-resistant
  • Comes with an integrated 6 ft., 2500 lb. high-tensile strength cords
  • Ursack highly recommends using an OPSak odor barrier bag or an aluminum liner (both not included) with the bag
  • This updated version features a tighter weave that's 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.
