If you're being all green and responsible with the resources you consume from Mother Earth by riding your bicycle everywhere, why not kick it up a notch by strapping on some panniers made of materials we've already borrowed from her Former billboards and banner ads join recycled nylon and PETE fabrics to make Green Guru's Carbon Cooler Pannier, minimizing your footprint while you're minimizing your footprint. The Carbon Cooler pannier pulls off some cool tricks while it's at it, too. For one, it's insulated to keep food or liquids cold en route, even on hot days. It's also entirely waterproof when closed, and there are reflective materials around the outside to heighten visibility in low light situations. Finally, when not in use, it collapses flat, but just in case you want to take it along, there's an adjustable shoulder strap included. Hard to argue with all that practicality and greenness, right Constructed from recycled billboard material actual prints will vary.
