Used this Thule backpack for about a year—it’s incredibly functional and comfortable, even when full. It fits a lot without feeling bulky. I love the stretchy mesh side pocket that holds a water bottle perfectly, plus there’s a hidden zippered pocket on the side for valuables. It was my favorite bag. The exterior looks great; the interior has minor cosmetic stains and could use a light cleaning. - Fits up to a 15.6" PC or 15" MacBook + 10" tablet in padded compartments (15.2 x 10.4 x 1.2 in) - Safe zone compartment with hidden pocket for phone, sunglasses, or other valuables - Large side-access storage with mesh divider for organizing smaller items - Pass-through panel for attaching to rolling luggage Mesh water bottle pocket + secure zippered side pocket
