superlight and not durable
Initally bought the smaller volume for light overnight canyon hiking in Grand Canyon. Got the size bigger to accomodate extra food and water. On the first trip out, I broke the stow-on-the-go trekking pole strap - since retied and good as new - and also broke one of the plastic compression cord buckles. I also noticed that one of the other buckles was definately stressed. Second trip into the Canyon, and I popped a seam on the inner pocket, the one accessed by zipper. All in all, I think its a good pack for the weight but not super durable. Having used it several times, I really like the ventilated back feature which also provides nice suspension and cushioning, but the pack definately will not withstand any abuse. I'm constantly worried about something failing on account of weight savings subtracting from component strength. I'll let you know if I ultimately keep it or trade for a more durable cousin. stay tuned...
