The maps are made of water-resistant and tear-resistant Tyvek material, which is lighter than paper. You can stuff the map in your pocket and you don't have to protect it from the rain. Material: Tyvek Width: 70 cm Height: 100 cm One map can fit a huge area, because we print on both sides of the maps. Thanks to the clever division of the pages, you usually only need one map on your hike, which also has many day trip destinations. We depict the steep slopes of fells and large hills with slope shading, which makes it easier to read the map.
