Everyday doesn't necessarily mean ordinary - or at least that's the case with the Peak Designs Everyday Backpack. This impressive 20-liter bag can carry everything you need in your day to day (and more with dual expandable pockets) in an endless number of configurations, thanks to its internal customizable FlexFold divider system. It also has a 15" laptop sleeve, comes with custom hardware, has hideaway straps, and features a slick and minimalist 400D nylon canvas weatherproof exterior.
