A waterproof, clear plastic case for maps and other documents with lash points on four corners. Papers with dimensions of around 5 1/2" (14cm) by 9 1/2" (24cm) will fit inside. A zip-loc closure keeps everything dry and secure. Stuff with a road map for quick access and with a notebook and receipts to sort out at the end of the day. The corner lash-points are a tough, rubberized and stretchy material large enough to pass Fastex buckles through so these can be mounted on Revelate Designs Sweetrolls and Harnesses. If you don't use a handlebar bag just lash directly to the handlebars.
