Hop on your bike and weave through traffic in the big city with the Timbuk2 Grid Backpack. This pack is built for going to and from work on your bike—even the roll top uses a bike tube as a closure. It also includes a side-access padded laptop sleeve, a self-draining side pocket for your rain jacket on wet days, and a magnetic front pocket so you can quickly access small items. Air mesh shoulder straps and a secure chest strap ensure your comfort, while reflective elements allow for safer dawn and dusk commutes.
