I bought a Blackjacket and was impressed by the overbuilt quality. I have not been able to use it a lot yet, but I like it best so far.

I have heard a lot of good things about the blackjacket, but I'm a bit worried about futzing with the sleeves. I like a cloth that simply has velcro along the bottom that can be opened up to get my loupe to the ground glass. The Harrison that Richard mentioned seems to fit the bill as it has a bit of elastic around the camera opening that provides a little tension, but the opening size is adjustable with velcro to fit various camera sizes.

Thanks for the suggestion.
