Mountain Gear says:
Urban, chic, classic, ARCTERYX's Hornet 18 is an organically designed daypack that has the looks to travel the most cosmopolitan places and the backcountry utility to see you there in comfort. Starting with a thermoformed backpanel, this pack keeps you comfortable with breathable spacer mesh at all contact points, gives you hydration options with a built-in system for your hydration bladder, and provides easy panel loading so that you can quickly access what you need, when you need it.
