Review on Kopack Backpack: The Ultimate Repellent Detachable Resisting Companion by Susan Zhao

The material isn't even water-repellent. Today I used the backpack I bought in the summer for the first time. I bought it early thinking I'll be ahead of the game by the start of the new school year. When I walked from the library to the car today in a light drizzle, everything in the "water-resistant" backpack, including all the documents, was soaked through. Even my iPad lying in the padded compartment got wet and ruined the wireless keyboard. In the photo you can see that everything inside is soaked to the skin. It has very comfortable shoulder straps and large compartments (the only reason I gave it one star).
