I bought this pack for my son's Diego halloween costume. He already had a cheaper backpack version that we bought at the Diego live show, but the two armholes on that pack don't fit him anymore (he's almost 4). This one is much more like the "real" rescue pack that Diego wears than any of the others I've seen on the market. The quality is very good, it's made from rugged backpack material, similar to what you'd see in sporting goods stores and very well constructed. Tha patch on the front is embroidered and looks very professional. We might even start using it as his regular pack for preschool. The velcro strap in the front is adjustable and so it seems that it could fit kids from about 2 to maybe 6. I had wondered from the listing whether it was officially licensed or more home-made, since I haven't seen this for sale anywhere else, but the tags look legit.
