For the price really good! At first I was a bit worried because my 1:25000 OS map didn't fit at all, then I realised I was being daft and the map actually goes in sideways in this design of case... Bit odd but not a problem. It was pretty robust and held up well on Dartmoor, map stayed dry. Basic model so it's only a 4 star map case but it does the job so if you want a cheap case go for it.
