Topeak's Pannier DryBag DX is crafted with fully seam-sealed and sonically welded 420/840 denier nylon with a roll-top closure for maximum protection in the nastiest conditions. Slideable hooks let you place the bag exactly where you want it on your rack, and the quick-release system makes installation and removal a breeze. Well-thought-out details include reflective accents for visibility as well as a handle and a shoulder strap for easy off-bike carrying.
