User Review: Garcia Backpackers' Cache
Every ranger likes to point out the added benefits of carrying a canister. And, they do help you cope with the extra pound + you're carrying. It makes a great stool. Your crackers don't get crushed. And, in a pinch you can use it to bail out your canoe.
However, these things are heavy. You'll definitely feel it alongside your titanium pot and ultralight tent. And, they are a little awkward to pack depending on the width of your pack.
But, this model is the bombshelter of culinary delights. There are other options like Ursasack and that clear canister (??) - both of which have had some issues. But, this one is virtually impossible to crack. Opening it requires a coin - which bears don't carry. So, you're safe there.
I personally like to carry the clear canister because 1. it's clear and I can see what's inside 2. it's a bit lighter.
