For long tours or spins around the block, Ortlieb's Ultimate5 M Plus handlebar bag keeps essential items at your fingertips. The lid has a rigid internal stiffener and attachment points for Ortlieb accessories (sold separately). Inside a set of dividers keeps your things organized and a zippered pocket holds valuables for quick access. A shoulder strap makes carrying it off the bike easy, mesh pockets hold extra stuff, 3M reflectors increase visibility, and if you have to put it down the square bottom keeps it upright. A lockable mounting system secures the bag to your bike even if you're not there to watch it.
