California-based riding gear specialist Nelson-Rigg claim their Sierra Dry Saddlebags are 100 percent waterproof, a claim we can back up after a long ride in torrential rain. Our riding gear was soaked, but everything in our Sierra Dry Saddlebags was perfectly dry. Made to last with aircraft-grade mounting hardware, they feature removable stiffeners to hold the bags' shape when empty and zippered liners to make packing/unpacking a breeze. Each bag holds 27.5 liters. Lifetime warranty. Available in black or yellow/black. $199.95.
