I needed a pack I could use with a bear can that was durable for the brushy, rocky, wet Olympics. This is now my favorite pack. It's around 3 lbs but has perfect dimensions for a centered can and my gear around it. I like that the pockets aren't mesh, which can get snagged by branches, tear and leave you dropping your items like Hansel and Gretel as you walk. I do have to use it with the full frame in place--just the foam frame is not enough support with the pack fully loaded but bear cans are required here so I can't imagine I'll get a chance to test it with just the foam frame and less weight. Highly recommend if you want a lighter large pack with the ability to carry a heavier load.
