I know it's an old thread, but maybe it will be a timely resurrection for someone.
If you want cool bear container you need look long and hard at the ULA Catalyst. It will hold more than you want to carry. It collapses down to hold whatever load you need to carry. Very well made. Very good load transfer to the hips. Relatively inexpensive. Made in the USA.
Hint: One outside pocket holds an MSR HUBBA HUBBA NX 2 person tent. The other side pocket holds a full Nalgene 3 quart soft canteen and an MSR Waterworks filter. Both pockets weren’t full. A bear can fits in the top horizontally.
Or consider the Osprey Volt 75.
It's one of their ""no frills"" pack. Doesn't have as many bells and whistles as other Osprey packs (and only comes in one size). As such, it's one of their cheaper packs, and only weights a hint over 4lbs.
I purchased the Osprey Volt 75 for a JMT thru hike... needed something I could carry a 20lbs bear canister (Bearikade Expedition loaded with 10 days of supplies).
The few negative reviews the pack seems to get has to do with fit (after all, this is a one-size-fits-most). I found it to be comfortable, and had it loaded with as much as 55lbs during my JMT hike.
Compare that to the Osprey Aether AG 70 or Osprey Xenith 75 that can weight 5 to 5-1/2 pounds for the same volume.
Hope, I help.
