Has anyone used or seen this pack? It's featured in the April 2012 Backpacker gear guide and it's rated a "versatile bargain" and "killer deal". It is a 40 liter pack that expands to 55 liters so the idea is you could carry a large load up to camp, drop some stuff off like food or your tent, and ascend up a mountain. Or similarly, you could hike to a camp, drop off stuff, and use it as a smaller pack for a day hike.
It weighs 4lbs so it's not ultralight but it costs only $199, which seems reasonable to me. Another cool feature is it has a removable closed cell foam (?) pad in the back which is used for back support. However, since it's removable, you could take it out and use it as a chair, sleeping pad, or even a splint for a sprained ankle, or something.
I don't *need* a pack right now but I am sort of a gear junkie so I was thinking about picking it up. What do you guys think? Any experience with this?
