Have to give it a 5 because it was on closeout at REI so the price was good. Pros -
1. Good quality construction and durable so far.
2. Rope straps are nice and actually work pretty well to hold the rope in place.
3. The waist strap is removable - works good when you want a casual pack to carry to the gym.
4. Waist strap is beefy enough to make a real difference when you're fully loaded down.

I used this pack out in Red Rocks this spring for some easy trad. I packed gear inside and hung the rope on top. When I got to the wall (Solar Slab). I threw the 2nd rope inside the bag with some water and Gatorade and wore it while climbing. It's maybe a tad big to climb with because it makes it harder to reach gear at the very back of your harness.

Overall a very useful pack.
