ISO: External Frame Child Carrier

I'm looking to buy a used external frame child carrier - Osprey, Kelty, REI. If you have one you're no longer using, please get in touch! Best, Sloane Farsight Media <http://farsightmedia.co/> | GSPIA <https://www.gspia.pitt.edu/> | @sloane <http://twitter.com/sloane>
