Great child carrier! Great strides have been made over the years with child carriers...and the Pogo does many things very well. Osprey's pack expertise is woven through the Pogo's construction, so the owner can expect many years of reliable use. As the "wearer," I found the pack very adjustable and comfortable for extended periods. The backpack is very balanced and I felt there was plenty of airflow so my back wasn't drenched...even after 4.5 hours post Christmas shopathon. We have to hide the pack. When my granddaughter sees the pack she cannot be consoled unless she is buckled in and I'm carrying her on my back. Perhaps it's the elevated perspective, but it's her favorite.
