Our family has gone so many miles with this pack! We didn't have a big budget when we first started hiking so found the first used pack on marketplace... Remy got used to it from the date she could hold her head up actually can still fit at four years old (yes, yes shes small for her age). While I wouldn't suggest putting as many miles as we did on it, I still can't say enough good for this light weight buddy! He is quite a squeaky pack now days, but still our best friend :)
Pros: *Large pocket for storage (it's huge!) *Pocket for cell phone)
*Very affordable (find used from $15 bucks!) *Close to the "carrier" (they can lay their head right on your neck) *Light Weight - the pack itself is extremely light weight! *Flexibly comfortable for child. *Adjustable straps for carrier
Cons: *Cannot adjust child *Some say the straps aren't thick enough- for me they were fine. *No cover (huge gone.. If your kiddo is a hat thrower or doesn't like the rain, your doomed!)
If you are planning on putting in the miles though we would suggest going with something like the Deuter packs as we talk about HERE. So many more options with it. But if you are looking for something quick and affordable - Snugli is the way to go!
