I picked up one of these second hand, it was good while bubs was light, I could have him on my back and walk our 2 dogs, but as soon as bubs was 10+ kgs I noticed the frame of the backpack would dig into my back and was quite uncomfortable. I've bought some padding to try and stop the problem, but I think it's a fault with the backpack. Worth testing it with a heavy child before you purchase one.
