If you just needs something to stuff and strap on. the Rookie will suit you. Free of tricky pocketing. the Rookie offers slip pockets for essentials -- laptop. u-lock -- and a secured zipper pocket for special stuff. Its no-nonsense. roomy interior can handle books. other bags. layers. and lunch. and its reflective zipper pulls are easy to tug and keep you a teensy bit safer while you cycle. Not exactly a rookie.
