We have a used maroon and black REI Piggyback Child Carrier for sale for $55. It is great for hiking and can accommodate a child up to 60 pounds. Here is a link to the carrier and I have attached photos, but this model is no longer sold. https://www.rei.com/product/705789/rei-co-op-piggyback-child-carrier

These are other more current models that all sell for over $200. Let us know if you'd like this one.  https://www.rei.com/c/baby-carriers.
