As my child grows I was finding my original kelty pathfinder wasn't holding her weight very well. This carrier is much better constructed and very solid feeling with a child weighing 35 pounds. However Kelty added a storage area that takes up way too much space and conflicts with my child. The torso area fits her well, but the legs get cramped by the new storage compartment on the bottom. The detachable backpack is all I need for our child's necessities as well as my own. The low storage compartment also makes it difficult to hike as the extra weight is way too low on the frame. The carrier comes with a mirror, but I bought a camping mirror for $2 that I used with my old one. In the end great construction, solid feel, but poor ergonomics.
