Built and designed as the big brother to Giant Loops Rogue Dry Bag, the Columbia is a much-larger 70 liters of storage that’s built into a completely weather and waterproof construction. That same construction also resists heavy wear and fits onto nearly any motorcycle—whether it has a rear rack / pannier rack or not.
Because of that versatility, you can position the Columbia in several ways depending on what works with the other luggage you have on the bike. But regardless of how you have it mounted, the double-ended openings of the Columbia let you have access to your packed items without unstrapping the bag, standing it up, and digging through all your gear.
Giant Loop also packed exterior features on the Columbia with a large, zippered mesh pocket on the outside—good for wet items like socks or thin items like maps and documents—lashing points for add-ons like the Possible Pouches, and extra d-rings if you want more attachment points to tie the bag down.
