Its no secret that most of us would prefer to spend as much time on our bikes as possible on any given day, and to help us get the most out of our two-wheeled friends Ortlieb offers the Trunk Bag. This handy bag rides neatly on your rear pannier rack, and offers a whopping 8-liters of space to pack in groceries and bulky items on the ride. It can replace your traditional panniers, or pair up with them to boost your loaded capacity for days when you've got quite a few errands to embark on. Built to hold up to serious downpours and road abuse, the Trunk Bag is crafted from waterproof polyurethane coated nylon that sheds water like its going out of style, while holding to to abrasion. It features two external non-waterproof neoprene pockets for items that can withstand some wheelspray, and a zippered internal pocket to keep your wallet and phone securely stashed. And since your rides rarely stop when the sun starts to dip, two lateral reflectors shine brightly under headlights to keep you visible when your adventures take you out past the light of day.
