Child Backpack Carrier (NR26)

This doesn't have a brand name tho I think it was originally from Amazon. The backpack and raincover are there but not the canopy. My daughter got this 2nd hand but didnt use it when she discovered the tear where one of the attachments joins the waist support and stabilises the backpack. I've attached a photo of the intact side and the torn side. It obviously needs a proper repair to be safe and stable
