Not really a recommendation, more a non-recommendation, which is potentially just as helpful.
I’ve got a Kata 3N1, which I bought for taking on my honeymoon as I wanted to take all my camera gear but also have something with enough room for all my carry-on bits on the plane; Kindle, magazine, bottle of water etc.
It’s a half decent bag, but there are so many small niggly things with it that make it a bit rubbish – silly things like the waterproof cover has no storage pocket; it’s just comes as a cover that you have to stick in the bag, which eats into the available space & is untidy; the Velcro for the internal dividers isn’t very strong so everything flops around, the tripod mount is just some really flimsy loose webbing straps that you have to find somewhere to store when not using (like the rain cover) etc…..
I’ve got a LowePro Sling bag (can’t remember the name now Slingshot 200, perhaps?) but that works so much better. It’s not as ‘feature packed’ and is too small for what I wanted – hence buying the Kata bag, but it is a much better thought out product .
