If you're looking for more storage in a sissybar bag, then you need to check out Dream Apparel's water resistant textile bag that's ready for any weather with its own rain cover with drawstrings. It's really easy to carry thanks to the strong handle and shoulder strap and it even keeps you safe by lightening you up at night with a stylish and functional reflective stripe across the large double zippered main flap. Measuring 13" long, 10" deep, and 10" wide, all three compartments are lined with a delightfully smooth textile lining. When you're ready to ride, fasten everything to the sissybar by two large Velcro straps and two nylon straps with quick release clips and hit the road.
