I had been looking at purchasing the Osprey Exos 58 for a while after reading reviews and trying one out at REI but I was hesitant to spend so much on another backpack. The combination of light weight while still providing a full fledged backpack (including a decent internal frame) was very appealing. When one showed up in the Campsaver Shed at a large discount I picked it up. It was classified as a used item with a "musty smell and one stain". I never noticed the musty smell and the stain turned out to be one small spot of tree sap. I scraped it off and cleaned the area. Overall, a great purchase for a fraction of the cost.
