The regs for the Inyo National Forest side say "container" (in contrast to the NPS which say "canister"). However, you might consider that the weight of the lightest weight approved canister (the Bare Boxer current spec is 1.6#) is now only 8 oz. heavier than the Ursack with the liner option. You can also use a canister to protect fragile gear (spare sunglasses, camera gear, electronics, etc.). I have the original heavier (1.86#) version of the Bare Boxer, and it fits in a day pack. It's just click it and forget it. I still have a Garcia, useful just in case there isn't a handy bear box when car camping, but it is yesteryear technology so I don't lug it on a trail. The Garcia is still the best stool, though.
