Kata is a Japanese word meaning, "how to get your a** kicked on the street." It’s also an Israeli company that produces high-tech paramilitary gear including beefy and functional bags.
The Kata S-312 – catchy, I know – is a compact and intelligently designed sling-style carry case that works great for grab-and-go. It has a padded camera compartment plus various other pockets for a cell phone, etc.
While other companies throw around words like ergonomic with no particular care as to its accuracy, Kata bags do it right with a sling design that is comfortable and fully adjustable.
