No need to choose between bear and critter protection. The Ursack AllMitey protects your food from all creatures great and small. While our standard S29.3 AllWhite resists being torn by bears, it is prone to small (less than 1/4 inch) punctures/weave separations. The AllMitey is virtually puncture proof. Not only will it keep out bears teeth and claws it will thwart mice, raccoon, squirrels, pine martens and other sharp toothed critters. It is made with a patent pending laminated process that combines the Spectra used in our S29.3 and Kevlar correctional fabric–the kind used in prisons to thwart shivs. The laminated part of the AllMitey is also water resistant. The seams, unless treated with seam seal, could leak..THE ALLMITEY WEIGHS 13 OUNCES–ALMOST TWICE THE WEIGHT OF OUR S29.3 ALLWHITE–BUT MUCH LESS THAN ANY CANISTER.The inner bag, when sealed with the closure, will hold about the same amount of food as our S29.3 AllWhite–650 cubic inches.. If packed only with freeze dried food, it will about hold about 35 servings of breakfast, lunch and dinner-six days of food for two people. There is a bit of additional storage space above the hook and loop fastener and under the cord enclosure, but this area offers less protection while still preventing bears from getting a food reward. The AllMitey comes with an integrated six foot, high tensile strength, cord, which is designed to secure the opening and allow it to be tied to a fixed object like a tree branch. Interagency Grizzly Bear Committee certified No. 5135. 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. Some units may have different color thread or rope than those pictured. NOTE: SOME WILDERNESS AREAS REQUIRE HARD SIDED CANISTERS.
