This canister is a little heavy, but it is bomb proof. It makes a great seat also. It was tight on space for two people for 4 days, but we made it work.

As of the summer of 2005, this was the bear canister of choice of the rangers I met in Yosemite & Sequoia/Kings Canyon. Even some of the competitor canisters have had their lids popped off by the wily bears. This thing is heavier than one would like, though.

The backpacker's cache works great.
With proper planning I was able to store food for 3 people on a 4 day, 3 night trip to the Rockies inside of one container.

They work well and pack easy. We did not have any bears test our containers on this trip but the containers were much easier than hanging bags. We used both internal and external frame packs and the containers fit well. 3 people with 7 days food in 3 containers. The containers were handy for seats and water containers in camp before stashing food for the night. The translucent plastic allowed us to identify meals in the container without opening.

We now save time spent trying to toss a darn rock with a rope over a branch with this. We also have used them as a mini table to share our dinner, or a makeshift, but not ideal, seat if it is raining. Just a tip though, always put the lid side down to the ground, so rain doesn't get in as easily.

Absolutely bombproof bear container I used in grizzly country in Alaska. Sporting goods stores proudly display nicked up samples that survived grizzly attacks. Negatives: tricky to use. Small opening and water does get in. Need a dime or a screwdriver (swiss army knife). If you are far away from resupply, this is the one to get.

On a trip to Yosemite we had packed the cache with food for three of us for three days. A mama bear and her cub just went by the cache and didn't even attempt to open it. We had hung up everything else that wouldn't fit in the bag. We were so proud of the "good" hang. Mama sent the cub up and they proceeded to devour while we watched helplessly.

Easy to use.
The only short fall is that it's a little tight for four days food for two
men. We made it work.
They should consider making a larger one.
