We were asked to produce this bag by a local cattle rancher. His requirement was for an all-purpose day bag with a wide shoulder strap that could comfortably carry the miscellaneous odds and sods that working cattleman would take on either a fortnightly trip to town, or else on ranch patrols: cell-phone, veterinary odds & sods, notepad, bank bag, revolver, palm top, Leatherman, binoculars, GPS, lunch, sweater, etc.
