are zing covers camera safe?

Hi,
I did a search to see if this has been mentioned but the search came up with nothing so I appologize if this has been taked about before.
I have a button close neoprene zing case (the ones that are one piece and the case closes by a hole wrapping around the lens). I'm wondering if this is safe for the camera. It seems like this would put some stress on the lens mount. I think that i'm probably better off traveling with my rebel xt in here than just out in the open, but i want to make sure it won't damage my camera.
Thanks
Vicki

I'm not sure if I'm understanding what you are asking. Are you keeping this case on the camera while you use it or are you using it for storage? If its just for storage while you travel I would go with something more heavy duty.
