Review on Durable Laptop Backpack: Water Resistant Anti-Theft Bag with USB Charging Port and Lock - Slim Computer Business Backpacks for Women Men - Fits 15.6 Inch Laptops - College School Student Gift by Darryl Blumenthal

Hardly a true anti-theft backpack without cut-resistant fibers and/or RFID pockets, but still a good laptop backpack for the price. The zippers seem to be rather weak. I think most men could just twist the fabric on top and snap the clasps themselves to unzip; However, this is something you would hardly miss walking and/or not having it in sight. Pockets on the inside of each main pocket (including an inner pocket that securely holds a laptop) keep your valuables from slipping out if a would-be thief cuts through your bag while you're walking. My biggest criticism of this backpack is that the laptop sleeve almost reaches the bottom of the bag; I would have preferred either buffer space or decent padding on the bottom for extra protection when putting the pack on the ground. If you already want to use an external battery, check the dimensions of the other inner pockets in the main pocket. My current PSU is too bulky to safely fit in one of these PSUs (assuming my PSU was released a few years ago and I think High capacity power supplies have since gotten a bit thinner). Aside from a few minor issues, I think I'll be very happy with my purchase for a while (as long as I place it gently on hard surfaces). This is by far the most comfortable backpack I've worn (it's thinner than it looks in the promotional photos).
