SANNIX Waterproof Map Case Transparent Map Cover with Clear Window and Neck Strap PVC Camping Map Case for Hiking (31x28cm) with Carabiner and Whistle

Just what he was looking for

Does exactly what it's supposed to do, keep your map dry. No need to pay more. The seal is a little fiddly but for the price it's worth the extra few seconds it takes to secure.

It did all that it said, great item.

Does exactly what you expect. Don't need 2 whistles. Carabiners are useful. I only really wanted the map cade which I'm pleased with. Recommended.

You get what you pay for, seal a bit fiddly at times

It would probably have been waterproof if it had lasted more than a couple of hours, a folded O.S map pierced through the seem rendering it useless

Very cheap compared to the competition, just big enough to take a folded OS map.
