Ursack Major S29.3 AllWhite


The Ursack S29.3 MAJOR AllWhite (IGBC cert. no. 3738) is the larger version of our classic S29.3 AllWhite. The Major holds about 50% more food than its smaller sibling and weighs 8.7 ounces. Otherwise it is identical.   The Major 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 Major weighs 8.7 ounces. It is about 24 inches in circumference (<8″ dia.), 18.5 inches tall and holds about 925 cubic inches (15 Liters). The Major does not come with an odor barrier bag (OPSak) or an aluminum liner–neither of which are made to fit the Major. Two OpSaks would be required, and must be purchased separately. We highly recommend OPSak, which is designed to always be used inside the AllWhite. Without the optional aluminum liner, your food may be crushed, ripped or punctured. Or, it may not–see: Bear in Camp: How Did the Ursack Perform? While the AllWhite is critter resistant, the Ursack Minor may be better suited for that task. See FAQs. 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. The Major is pictured here next to our standard size Ursack. 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.

Note: Due to the difficulty in weaving high tech Spectra, our supplier is not always able to deliver pristine white fabric (the only color available). Your Ursack may arrive with minor cosmetic blemishes. You won’t see these once you have used Ursack in the wilderness, and these in no way compromise the performance of the product.

Shipping cost is based on weight plus special handling for oversize items. All our fulfillment is now handled by Amazon, and our products ship from their warehouses as either economy, expedited or two day shipping as those terms are defined by Amazon. There are no other shipping options.
