From touring, to commuting, to social group rides, Giant's ST Trunk Bag is ready. It attaches easily and quickly to almost any rear rack (sold separately) and includes a built-in rain cover that keeps your gear safe and dry. Inside, there are adjustable foam compartments to protect and organize your belongings, while two zippered side pockets and a single zippered rear pocket increase the overall storage capacity and versatility. A shock cord across the top of the bag gives you a convenient place to tuck a jacket or spare clothes. When you reach your destination this bag easily detaches from the rack and, thanks to the removable shoulder strap, is a joy to carry with you.
