My smartphone measures 13.5 x 7.0 x 1.5 cm and fits perfectly in this bag. For that I can Tatonka Neopren Zip Bag, black, recommended in 2933 that I bought later me, because the bag was too small on my drinking belt. The Tatonka shell has a dimension of 15 x 10 x 2.5 cm (indicated 15 x 8 x 4 cm), and is ideal for a smartphone normal size. You can without any problems on the belt attach vertically or horizontally, although looks a bit Globig, but serves its purpose and does not bother me while walking, jogging or cycling.
