We have used the Borch laminated maps on several international trips and love them. They are durable, have very good detail, and are great for the preplanning we do. They can be taken out in the rain with out fear of disintegration. They don't break at the folds like other maps. Routes can be drawn directly on the map, notes can be written on the surface, then as you gain information the trip details can be wiped clean, or revised with a wet cloth. I have used ballpoint, grease pencils, and even Sharpies (I like the sharpie the best.) All can be cleaned off or modified as needed. We are currently in the planning stage of a trip to Chile and Argentina, and can not speak to the accuracy of these particular maps, but if past history is any indication of quality these too will be great.
