This is a baby backpack with a detachable anti-lost harness that I purchased a few years ago for my older child. I used it 3-4 times, but I'm selling it now because I no longer need it. It has a denim-like color, but it's not made of cotton denim fabric. It's a smooth, nylon-like material. The design is simple, easy to use, and lightweight. There was a patch on the lower right pocket, but I removed it myself by unpicking the threads. It's not very noticeable that it was ever there. Please understand that this is a used item. I'm also selling many other kids' and baby items, so please take a look! If you have any questions, please ask in the comments.
