Ortlieb's Sport-Packer Plus is an awesome bag for loading up the front rack or sharing the load with smaller bikes. This fully-waterproof bag features a mesh zippered pocket inside for organization and a drawstring flap to protect against dust, humidity, and snow. A removable shoulder strap makes for easy carrying, and bottom feet help the bag stand up on its own. Ortlieb's QL2 mounting system makes getting the bag on and off a bike easy and is compatible with nearly any rack design. Large reflectors improve visibility when riding at dusk or dawn.
