How much do framed baby backpacks support?

Question

I'm looking at getting a metal framed hiking type back pack. What is the upper weight/age limit to these? Here's the one I'm looking at getting. http://eastidaho.craigslist.org/bab/796313648.html Are these too big for toddlers?

Answer 1

it should say on the box!

Answer 2

they only go to 25 pds. Why don't you look at the ERGO carrier, those metal frames are horrible for you back! The ergo is great and comfy I use it all the time
