Question: Two critical specs: Weight and volume?
Document: This is the industry standard canister. Should last as long as you need it. We've dropped it across granite rocks a few times, and it's just fine. Only issue is its weight, as its a bit heavy, but that may be necessary for protection purposes.
I live in an area where campers routinely run into black bears. Bear proofing your food is a necessity here.This is a round keg that measures 8.5&#34; x 10&#34;. It's large enough to hold several days of food, especially if you pack creatively. The lid is secured by two flush-mounted screws.
One afternoon, my lovely large German Shepherd (Blitz) discovered how to get up to where we keep her chicken jerky treats(non chinese meat ones) and proceeded to devour two whole bags. At first I was just mildly annoyed. Until I returned home from work the next day....There was a poo-pocalypse the likes of which I wouldn't wish on my worst enemy. To say it was like chocolate icecream from the depth's of Satan's bowels would be putting it mildly. It. Was.
After rotating the latches, I just had to scratch with fingernails to get the lid to lift, or flip it over and shake. Not a big deal but fyi.In terms of practicality, if I had it to do over, I would go with all large size canisters. You just need the space, and a canister is going to occupy a percentage of your pack no matter what. The smaller volume canister consumes about the same amount of backpack space and the large.
you can't open the lid with out tilting the whole canister upside down. it's a simple design flaw. Other canisters I've used allow you to press one corner and the other side of the lid lifts up to remove the lid, but this one doesn't have that option. Other than that, it served it's purpose.
as it is required for the park system out here, it works well easy enough to get in to - same size you can rent from the parks.
This is small enough to fit easily under the seat of my Burgman 400. I live near the Sierra Nevadas where we have lots of bears. I am a solo camper and  this easily stores about 4 days of dehydrated food. spices, Tooth paste and soap.For solitary motorcycle/backpack camping in primitive camp grounds, it is great.
This is a large container, and looks like it would prevent a bear from gaining access to its contents. It holds a lot of food, but it is rather heavy. I don't think there is a lighter one available with this strength and capacity though.
This container is very sturdy, you can sit on it. Opening the lid is easy and I can use my nail to open it. When you try to open, sometimes you need to hold the container sideways or upper side down. It has decent amount of room and I think this one is already big enough (not too big for the backpack).
This canister is okay for intended use but difficult to open & close, both the locking device and to pry open, especially on frosty mornings.
