For critters-not bears. The Ursack Minor is made of a fabric woven from Kevlar “bullet proof” fiber. The highly cut resistant weave prevents sharp toothed critters from getting your food. Ursack Minor will NOT protect against the strength of a bear. The Minor weighs less than 5 ounces, and is 8 inches in diameter, 13 inches tall and holds about 650 cubic inches. If packed only with freeze dried food, it will hold about five days of food for one person–maybe more. It comes with a hook and loop closure and an integrated loop to clip a carabiner or tie a cord to. It does NOT come with a free odor barrier bag (it uses a 12 X 20 OPSak) or additional cord. Limited Lifetime Warranty. We will replace, or refund the cost of, any properly deployed Ursack Minor in which a gap, tear or hole larger than 1/4 inch is caused by a wild critter (excluding bears). We do not warranty Ursack Minor against bear attacks.
