Do you enjoy cycling to work or do you often go on a day trip during the weekend? Use the Thule Chasm 15 inches 26L to transport all your belongings dry and in an organized manner. This water-resistant backpack protects your 15-inch laptop from a rain shower and the ventilated back keeps you comfortable and free from sweat stains. The spacious main compartment offers enough space for a stack of documents and rain pants. You can take your laptop out of the bag through the special side opening, without having to search through the main compartment. You can also neatly store your phone, wallet, and chargers in the Chasm 15 inches, thanks to the closed top compartment. 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.
