The Thule Subterra Travel Backpack 15 inches 34L offers optimal protection for all your electronic devices. The backpack has several padded inner pockets for your phone, charger, and tablet, as well as a 15-inch laptop. The backpack also has a power pocket, in which you can store your cables conveniently. Do you cycle to work regularly? The ventilation systems in the back ensure that you won't arrive all sweaty. The Thule Subterra Travel Backpack also has a removable clothing bag so you can store your clothes. Do you prefer to bring the backpack on holidays as well? In that case, simply attach it to the back of your trolley suitcase with help of the smart sleeve.Note: the size of your laptop, like 15-inch or 17.3-inch, is the screen size, not your whole laptop. If your laptop has wide bezels around the screen, it's better to choose a laptop compartment that's a size bigger. That way you'll know for sure that your laptop fits.
