The Thule Accent is made from 100% recycled polyester and you can easily take it with you to school or work. With a 23L capacity, you can fit multiple books or files in the bag. You can also safely take your 15-inch laptop or 10-inch tablet with you in the padded compartments. The Accent Backpack has 1 main compartment with multiple accessory compartments. This way, you don't have to search for your stuff for long. You can safely store your smartphone or sunglasses in the front compartment with SafeZone compartment with a removable bowl-shaped exterior. You can also take your bottle of water with you in the designated side compartment. Is it warm or have you packed many objects? Thanks to the ventilated back, your back stays cool. Note: the size of your laptop, like 15 inches or 17 inches, is the screen size, not the size of your whole laptop. If the bezels around your screen are wide, choose a laptop compartment in a larger size. That way, you can be sure your laptop fits.
