Review on Leakproof Insulated Cooler Backpack By Piscifun - Lightweight Soft Cooler Bag For Men And Women Ideal For Picnics, Fishing, Hiking, Camping, Parks, And Day Trips - Keep Your Lunches Cool And Fresh! by Ronald Duguay

I bought this for the pricing and the good reviews. However, I wouldn't call it water proof on the inside. You can only fill it up about as high as the zipper comes down on the sides. The zipper leaks terribly and if you have ice in there that begins to melt, you will get soaked if you are wearing the back pack. If you bend over even slightly, the water from the melted ice will come out of the zipper. I think it needs a thicker liner on the inside and the zipper should be oriented at the top of the bag rather than coming half way down the back pack. Maybe if you just use ice packs, you won't get wet, but that isn't real convenient for going to the beach or camping and planning to come back with a lighter load. I apparently missed the return window. Thought it was 90 days for Prime items, but I guess that isn't standard.
