Review on MANCIO Slim Laptop Backpack with USB Charging Port - Vintage Tear Resistant Business Bag for 🎒 Travel, College, School - Casual Daypacks for Men and Women - Fits up to 15.6Inch Macbook - Black by Jay Blo

I plan to use this at school where there is a lot of work and books to carry. Let's see how it holds up. The material is good, but supposedly water-repellent. It was misleading but the contents inside don't get wet. There are 2 layers in the top flap/lid so the outer one absorbs the water and the inner one keeps it out. The biggest problem is that the water bottle pockets are incredibly small. The non-USB side barely fits the *fake* water bottle, which is thinner than most regular water bottles. The USB port side doesn't fit in a bottle, but it's great for holding a phone. However, I don't recommend putting your phone there depending on how many pickpockets are around you. Edit: The quality is pretty bad and after a few months of use, threads are snapping all over the place. The laptop bag doesn't protect either - my laptop bag ripped at the corners (and I don't drop my backpack on the floor and such). It would be better for light, occasional use - if you intend to use it all the time I would recommend paying for a more expensive, higher quality backpack. The best backpacks only cost 2-3 times more and last 5 (or more) times longer.
