OS Explorer Map and OS Landranger Map - Active Series
The popular and durable Active map series contains the same information as the standard versions of OS Landranger Map (1:50 000 scale) and OS Explorer Map (1:25 000), but they are treated with a lightweight plastic coating. This not only protects them from the rain and mud, it also enables the maps to be written on with washable ink. You can highlight your favourite routes, waypoints and landmarks and easily wipe it clean later on. The durability of this type of map makes it a very popular choice for extreme outdoor sporting activities, and also with groups who share maps on weekend activities.
