- Bag measures about 8 x 19 in. (diam. x H) when cinched closed, holds about 650 cu. in. (10.7 L) and weighs 9.5 oz.
- By laminating ballistic-weave fabric with Kevlar®, Ursack has made a soft-sided container that will thwart entry attempts from bears, mice, raccoons, squirrels and others
- A very rough rule of thumb is that, if packed only with freeze-dried food, the AllMitey can hold up to 5 days worth of food for 1 person
- Secure the bag opening and tie the bag to a tree branch with the integrated 6 ft., high-tensile-strength cord
- Ursack recommends using an odor-barrier bag as a liner (not included)
- Certified bear-resistant by the Interagency Grizzly Bear Committee
- The IGBC list is relied upon by many wilderness agencies but not all; wilderness restrictions may still apply depending on where you travel—check before you go

Not bear proof at all
Woke up this morning to find the bag still hanging from the tree but with the bottom shredded and all the food gone. This product does not work. Its no where near bear proof or even close. Do not waste your money unless you like to go hungry in the middle of your backpacking trip.
One of the toughest bear bags on the market!
[This review was collected as part of a promotion.] If you need a bear-bag for the back country - this one has what you need! Cavernous tunnel design that fits easily in 50L+ packs - cinch cord on top, and enough kevlar to keep a dinosaur from getting into your chow! Disclaimer - I only had a 5lb critter to do product testing, but, after fervent effort, she could absolutely not scratch or bite her way to the peanut butter snacks inside - and the bag still looks brand new! Seriously - this bag would be tough to bust. When I am expedition kayaking in the far north, PNW, AK, or climbing through the rockies - this is gonna be my go-to vault for food!

DO NOT BUY
Harmful to bears that will easily rip open this bag. I really regret trusting it. It should be recalled by rei. I feel bad that the bear ate human food and that I contributed to changing it's behavior and diet. Also losing your food when you are 10 miles out is very inconvenient. Do yourself and bears a favor and buy a bear vault.
Useful The 1st Night In The Backcountry
First night used, bear walked through my campsite. The Bear Bag(with odor proof lining) was about 100 feet away from my tent, the bear kept going. Luckily nothing in my pack - next to my tent - or in my tent caught the bear's attention. I have a Bear Vault 450, the Bear Bag has more space per the specs, and most importantly, for my likes, it can compress down to the amount you have in the bag. The BV is solid and takes up a lot more space. The Bear Bag also weighs much less than the BV. A great feature that has helped me to get my pack base weight to about 18.5lbs.
Plenty big and black bear proof
Brought my son out for an over night in the White Mountains. Packed 2 days of food for myself and my teen son. Tied the bag off for the night and we did have bear visits. I used an OP bag inside but the bear must have smelled something because he tried to get in. Lots of scratch marks but completely successful at keeping the food away from the bear. The bag is stiff but I suspect with use may become a little more malleable. Very light and easy to fit in the backpack unlike rigid canisters. Thank you for this great product.
Lighter than a cannister, but not much room
Bought this because everyone talks it up and I get tired of hauling my canister around. There's no way it's holding 5 days of food unless you are bringing homemade food/ingredients or repackaging your backcountry freeze-dried's. Not even close. I can get three days worth of freeze-dried's in it if I don't velcro the inner seal shut and smash them in to the point of nearly bursting the packages. Yes it's lighter than a canister, and if you're only out for a couple days it's a decent option. Otherwise bring something bigger or plan on hanging your entire pack. My bad for trusting the web and waiting till two days before leaving to actually test it out...
Not an obstacle to a bear
My food was in a zip lock bag, in an odor proof plastic bag, in the Ursack. I tied it as recommended and fastened to a tree as recommended with a heavy duty carabiner. Woke up one morning with the bag exactly where I hung it and seemingly underserved when seen from afar. But on closer inspection, the bottom was in shreds, and the plastic food wrappers all shredded and their contents presumably in the stomach of a satisfied bear.
has worked for me so far
I carried the 2.5 lb Bear vault for a thousand miles on the AT last year. Then I switched to the almighty ursack that's only half a pound plus. I have since completed 1100 more miles on the AT and 230 mi on the CDT up in Idaho Montana border. I greatly appreciate the lighter weight and easier packing and I have always kept my foods and smellables in loksaks. No animal has bothered my ursak at all. When it's going to rain I have been putting my ersack in a dry bag with the ropes hanging out and when I tie it to a tree I lay it up on a branch as high as possible which means 6-7 feet up. That has kept my ursac dry in rain. I am always careful with my smellables, and in areas where it's clear there have been bears, my ursak is fairly far away from my tent, maybe close to 100 ft. Try to be aware of places where there's bear pressure. Talk to other hikers and keep an eye on what may be in the logs or on farout. In areas where there are few hikers & backpackers, the bears don't know a lot about ursaks and they're probably quite safe. From what I have heard, the story is different when there's been problem bears. I doubt it even matters whether the bag smells. If bears have already learned that bags that look like an ursack contain food they will go for them. There are plenty of people with ursacks who do not use smell proof bags like loksaks. What can you say? the bears learn and once they learn that bags hold food we're all at risk. Finally, don't believe that bear vaults are the answer either. Since the AT started requiring them in the south this year, the bears are already learning to pick them up and run away with them. This info is published on the ATC website, although it's not always easy to find. Give a bear long enough and it'll find a way in.
OK only in low humidity.
The downside of the ballistic fabric is that it absorbs moisture. Not talking about direct rain getting in through the draw string top. This is about any dampness, even high humidity, that the exterior of the bag encounters gets absorbed through the fabric and into the interior. The moisture does successfully seep back out during the day while the Allmitey is in my backpack, soaking the backpack and anything else touching the Allmitey.
Rodents can be as bad as bears!
A must have for securing your food from critters big and small. If you are not car camping, then you'll want to ensure the little and big noses don't find your provisions. Use with the plastic Opsak bags so they won't even find your food. I am able to fit at least five days worth of commercial freeze dried food and snacks without a problem. I would even bet that if I dehydrated my own food and bagged it myself, it could be close to ten days with of storage. This does not weigh as much as the canisters, can fold down to reduce bulk as the backpacking progresses, and is so simple to use. The rope is reflective and there is a little tag that shows you the knot to use to secure it. All it takes is one mouse, squirrel, raccoon, skunk or bear to get your food and you'll be wishing you would have taken this advise.
