The Ursack Major (which replaces and is identical to the  S29.3 AllWhite (IGBC cert. no. 3738) is made of “bullet proof” UHMWP 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 7.6 ounces. It is about 24 inches in circumference (<8″ dia.), 14 inches tall and holds about 650 cubic inches (10.65 Liters). If packed only with freeze dried food, it will hold 37 single servings of breakfast, lunch and dinner. Video: how much food fits?  (or 57 tennis balls–see the picture).  The Major 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, ripped or punctured. Or, it may not: We highly recommend OPSak, which is designed to always be used inside the Major. While the Major is critter resistant, it is less so than the AllMitey or the Ursack Minor which may be better suited for that task. The newest version (which is the only version we sell) of the Major made since about April 1, 2015 has a tighter weave and more than double the tear strength of previous models. 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 Major 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 send pictures of 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 UHMWP, our supplier is not always able to deliver pristine black 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.  Some units may have different color thread or rope than those pictured.

Some areas require hard sided canisters. Check first.
