The Thule Lithos 16L Backpack features a padded back panel and shoulder straps. Made of polyester ripstop, there are dedicated, padded slip pockets for a 14" Windows laptop or a 15" MacBook, and a 10.1" tablet. Stay visible in low light conditions, thanks to the integrated blinky light lash point. Access the main compartment through the adjustable flap closure that secures with a 9-hook buckle, which also holds a zippered interior mesh pocket. A side pocket lets you carry a water bottle, and a stash pocket holds your phone or sunglasses.
