The Buca Boot is the first bike-mounted storage system that provides the flexibility of an open basket with the storage security of a car trunk. Use it open to pile in large items, lock it closed to keep your stuff safe and dry. Secure, waterproof, beautiful. Now you can go where you want, with what you want. The Buca Boot is made of impact resistant ABS plastic, beautiful marine grade wood lids (sourced and hand finished in Boston, MA) and nautically inspired brass plated handles. It attaches securely to any standard bike rack. When open the Buca Boot also expands to include side pannier bags made of waterproof rip-stop nylon canvas, available in three great colors.
