This is a GREAT hiking backpack, I've included an outside review of it, it's sort lightweight while also being very heavy duty and making it easy to carry even heavy children without destroying your back. If you intend to do any sort of hiking or even carrying your child for long periods of time (such as going to an aquarium for hrs, we had a double stroller and 3 kids so we used this instead of 2 strollers). These backpacks new go from anywhere between $130-$250. Asking $50 for this one (VERY clean).
