Features a fully padded main compartment to protect items if you take a spill as well as a submersible roll top closure. We use knurled welded seams so you can hose it down along with the rest of your bike after a muddy ride. It fits on most bikes with two velcro adjuster tabs along with a pull chord stabilizer strap to keep the bag from rocking forward. Like the rest of our Knurled Welded™ series, we made the Handlebar Bag our of a 600 Denier poly with a waterproof PU coating and then welded the seams with our patented Knurled Welded™ design to make the only welded bag construction that can live up to our standards. Guaranteed for life.
