Ursack Major

The Ursack Major is made of bulletproof UHMWP fabric and is designed to prevent bears from getting your food in their territory. It weighs just 7.6 ounces, and is usually combined with an odor barrier bag (OPSak) or an aluminum liner, purchased separately. The Ursack Major has passed the Interagency Grizzly Bear Committee test, and was placed on its bear-resistant products list that is relied on by many wilderness agencies.
