Query: Defective Zipper

Don't let the low price influence your purchase. You get what you pay for!! My Coleman backpack zipper broke on my first attempted use. Coleman Warranty Service was no help since I didn't buy it from a Brick and Mortar store. There is a big reason why these are selling so cheap, "They are Cheaply Made". I will never purchase Coleman products again!!!!
