My girlfriend got me the Gregory Paragon 48 as a Christmas present last year and the funny thing, she doesn't like hiking or backpacking so she's probably giving me a hint and wants me to get lost in the woods! lol It's pretty similar to the Osprey Krestral I believe. It's weighs 3.5lbs, comfortable, and carries the weight really well. As far as durability? I've only taken three trips with it so I don't know yet, but its solidly built. If you're looking for a backpacking pack, check out my video going over the pack.
