Very sturdy, well cushioned inside, re-arrange-able compartments, roomy, not obviously a camera bag, affordable.

It's not also a jet pack---jk what do you want for 50 bucks you're not going to do any better than this. With the money you'll save you can buy some extra lens filters.

The Kata Dr 461 is a nice sturdy bag, thoroughly padded and roomy. Padded Velcro compartment dividers in main storage part of bag can be detached and arranged however you want to fit your gear. Plenty of room for a decent sized DSLR/SLR with a big honking lens on it and room for two or three more lens. Second compartment has plenty of space for extra batteries, storage cards, notepad--whatever. Best yet the bag easily passes for an ordinary book bag style back pack--IE; it doesn't scream "expensive camera and lenses in this". Definitely recommend it and fairly affordable. I paid $60 for mine, you can get it online from Amazon or B&H or wherever for about 50 bucks. A real bargain, I love mine.
