Chromes' Knurled Saddlebag Rolltop 20 is designed for touring, bike based adventures and hardcore all-weather commutes. Guaranteed for life, Chrome have used a welded construction to make the Rolltop 20 all but actually bombproof.
The Rolltop 20 mounts to your bike's rear rack via a custom mounting system which is included with the bag. The bag is 100% waterproof even when submerged in water thanks to a roll top closure and a waterproof outer that can withstand 800lbs of pull strength. Chrome's Knurled welding technology allows them to create these hardened, harsh weather panniers 70% lighter than traditional waterproof bags.
