I have a Kelty kid carrier and it is awesome except for being able to take much of anything with me due to the limited space. I had purchased a RIBZ front pack for using while hiking with my backpack but quickly found its usefulness with the Kelty. I can carry snacks, camera, that juice cup, and even the rain gear. Up to 10 pounds of essential gear can be easily added with this front pack.. I loved it so much I became a rep... check out my posting.. I am selling them for less than the company who makes them!
