I find the bag ideal for my newly discovered hobby geocaching. I get loose headlamp, UV light, GPSr, notebook, camera, mirror, pocket knife, multi-tool, spare batteries, magnets and a 0.5l bottle into it. For pins there will be extra 2 Einsteckmöglichkeiten. The Tashkent can be adjusted well and therefore fits perfectly. So you have the most important at your fingertips.
