Eggsnow Universal DSLR SLR Camera Insert Partition Shockproof Padded Liner Nylon Construction Waterproof Case Bag 12"x 5"x 9" Army Green (A2)

Nice padding on all sides. I use it to cary my EOS-1D and one lens (16-28mm) and it all fits snugly and safe. Note: if you have a 1D size camera body (or a standard DSLR with a grip) this will be just a bit too narrow (front to back) so it will bulge just a bit. I have this Jansport backpack and it fits perfectly http://amzn.com/B0007QCQGI (I measured before ordering).

Had a messenger bag I decided to convert into a camera bag and used this product to protect my equipment on the inside. Simple, but good quality and adjustable (also comes in different sizes so check on how much gear you have). Much better alternative to paying $75-$100 for a dedicated camera bag.

Totally huge for my Canon T5i. Bulky. So large it wouldn't fit in any backpack you could have.

very good
