Ursack : Bear resistant canister for outdoor activities

Ursack is a 7.3 ounce, highly bear-resistant, odor resistant flexible bag designed to protect food from bears and other critters like squirrels and mice. Ideal for backpackers, guides and other wilderness users, Ursack is made of bullet proof Spectra (S29) fabric. The Ursack Hybrid is simply a combination of the S29 AllWhite and our heavy duty aluminum liner. With a combined weight of 1 pound 2 ounces, the Hybrid is less than half the weight of similarly priced hard-sided canisters.
