The North Face Women's Vault is a daypack specially designed for ladies. The back and shoulder straps are narrower than with a normal backpack. You take your laptop safely to school or work in the padded 15-inch laptop compartment. You will also find enough space in the main compartment for your packed lunch and a small stack of books. This way you organize your things organized and you never have to search long. The backpack carries comfortably due to the padded shoulder straps. The back panel of mesh material provides cooling on hot days. Use the chest strap for more stability when you get on your bike with the backpack.Note: the size of your laptop, such as 15 inch or 17.3 inch, is the size of the screen, not of your entire laptop. If the edge around your screen is wide, choose a laptop compartment in a larger size to be sure. This way you know for sure that your laptop will fit.
