The zipper on this product messed up after less than a month. This case fits the Canon XSi with kit lens pretty snugly. However, I do not like how it hugged (or did not hug, rather) the camera. If you have the Canon EF-S 55-250mm f/4.0-5.6 IS Telephoto Zoom Lens attached to your XSi, it will not fit. Also, I'm a little embarrassed to carry this case around, because unlike the pictures online, in real life it looks like the seat of a bicycle.... so it looks like I'm carrying a bicycle seat (or as my sister likes to say -- that crotch piece) around.
