THE BILTWELL EXFIL-48 BACKPACK Like all EXFIL gear, the 48 was designed by bikeriders for bikeriders. Features include compression straps that do double duty as mounting straps, so you can fasten your backpack to the sissy bar to give your shoulders a break on long rides. Packed with enough storage capacity to gobble up 48 12-ounce cans of your favorite beverage.

One main and two secondary compartments hold 48 12-ounce beverage cans—that's two cases of cold beer to get the party started if that's your mission. The lower secondary zipper compartment has a PVC-treated tool caddy and an internal zipper pouch to hold wrenches and small gear securely. The top secondary compartment houses an internal zipper pouch, and all three compartments have hi-vis orange nylon lining to make spotting contents easy. The padded shoulder straps feature an adjustable sternum strap to stabilize heavy loads. Cinch straps around EXFIL-48's perimeter do two things: compress loads for greater stability, and fasten the bag to your sissy bar when it's time to hit the highway.
