I have a bunch of old map cases that work perfectly with my eclipse handlebar bag- they are folded in half and have snaps that fasten it. They fasten around a nylon sleeve on top of the handlebar bag. The only problem is, that they are yellowed from age since they were purchased new 25 or so years ago.
Are there any new cases that resemble these? Or do I just go the ziplock bag route?
I'm only looking for a plastic case, not a handlebar bag.
