I recently purchased the iFrogz wooden "Koala" case (http://www.zagg.com/ifrogz/cases/apple-iphone-5/natural-cases-covers#Koala). I absolutely love it for its super slim design and general look. It doesn't protect the device all that well from a fall obviously, but I just couldn't handle my first chunky protective case. Having said that, I would like a little bit more protection in addition to the iFrogz case. Are there any good wallet or sleeve cases out there that would fit an iPhone 5 that already has a slim case? I'm kind of paranoid about purchasing one of the ones I see on amazon, as I'm concerned my phone with its iFrogz case simply will be too tight of a fit. I plan on taking the phone in and out of whatever sleeve/wallet I get regularly too, so I wouldn't want something that's a pain to remove the iphone from. Advice? Tips? Thanks!
