Ursack S29.3 AllWhite
The Ursack S29.3 AllWhite (IGBC cert. no. 3738) is made of “bullet proof” Spectra fabric and is designed to prevent bears from getting your food in their territory. It comes with an integrated six foot, 2,500 pound tensile strength cord. The AllWhite weighs 7.8 ounces. It is about 24 inches in circumference (<8″ dia.), 14 inches tall and holds about 650 cubic inches. A very rough rule of thumb is that if packed efficiently, Ursack can hold about five days worth of food for one person (or 57 tennis balls–see the picture). The AllWhite does not come with an odor barrier bag (OPSak) or an aluminum liner. Both must be purchased separately. Without the optional aluminum liner, your food may be crushed or punctured. We highly recommend OPSak, which is designed to always be used inside the AllWhite. While the AllWhite is critter resistant, the Ursack Minor may be better suited for that task. The newest version (which is the only version we sell) of the AllWhite made since about April 1, 2015, dubbed the S29.3, has a tighter weave and more than double the tear strength of previous models. There is no good way to test its critter resistance, but so far it has been excellent. Pictured here with and without optional aluminum liner. The Ursack with improved Spectra seams (beginning April 2014) passed the Interagency Grizzly Bear Committee test and was placed on its bear-resistant products list on July 31, 2014. That list is the one relied on by many, but not all, wilderness agencies, and restrictions may still apply–check first. See FAQs.
Limited Lifetime Warranty. We will replace, or refund the cost of, any properly used Ursack S29.3 AllWhite in which a gap, tear or hole larger than 1/4 inch is caused by a bear. This 1/4 inch standard is the criteria used in the Interagency Grizzly Bear Committee’s test protocol. We ask that customers return any damaged Ursack to us for inspection. For more information about the risk from raccoons and other critters, see FAQs.
