The Level8 15" & 17" Atlas Backpack is a workhorse backpack that will haul your 15-17" laptop along with a small mountain of additional "stuff" with a bit of style. a ton of protection. and a lot of comfort. Thanks to it's adherence to TSA standards. your laptop can ride through the X-Ray screening station while remaining in the "checkpoint friendly" laptop section. There are four things that are critical for a travel/daily use laptop backpack - rugged construction. ample and organized storage. protection for the laptop. and comfort (when overloaded!) The Level8 Atlas is a winner on all of these.
