This product hasn't changed for at least 10 years. Why? Well, it just simply works. Made of neoprene, it is so strong yet very flexible, even in the cold. Also it gives you a complete view of the map, and both sides too. It is easy to fit the map in, it is easy to release the velcro closer and refold the map, it has a good lanyard, it is as convenient as a map case can be. I have had one for a good ten years and it is still going strong if a little yellow now. When I bought it I never thought I would have it so long, as so many of it's predecessors had failed. I'm getting another one as nowadays, I scan and copy sections of maps and guides and use these on the trail. Much more convenient than taking the actual documents, which can be bulky. Also, my eyes are not as good as they were and to enlarge a map so I can see it easily is a real benefit. When the trip's over, I just destroy the copy, including all the marks I've made on it, and my original map is ready to use again.
