The AxelPack, Axel Schoevers Chart Case
Axel's chart case is one of the only truly waterproof chart cases we've found. It's double ended rolling closures keep water out even under extreme conditions and also make it one of the few variable width chart cases on the market. The plastic tubes slide off to allow you access to your maps and also provide protection when the map is on your deck. Clips on both tubes allow you to clip the map case to your deck-lines..
