The Ursack ALLMITEY offers the ultimate in bear and critter protection for your food. It weighs just 13 ounces, and stores approximately 5 days of food for one person. It's virtually puncture proof. Not only will it keep out bears' teeth and claws, but it will also thwart mice, raccoon, squirrels, and other sharp-toothed critters. It's backed by a limited lifetime warranty, where Ursack will replace or refund the cost of any AllMitey that has a gap, tear, or hole larger than 1/4" caused by any wild animal.
