I managed to pickup a black version of the Body Glove Satin Pro Case from AT&T. It's pretty good and currently my favorite option available. I had the Tudia in gray before this case, and while it was a great fit, it didn't pack enough"style" for me. Prior to these 2 cases I have tried all the other cases at the AT&T store and the problem with most of them was that they were either too bulky, and/or had horrible fitment - as in, the buttons were terribly hard to press. This case has openening for the awesome buttons the s6 active has, and since it's recessed, I'm no longer accidentally hitting that active key (which is bound to open my garage lol).
Also, I believe this case is quite new, as it's one of the few cases doesn't have that additional "mystery hole" to the left of the lens that almost every other case has. I snagged it off ebay, new, and for less then the white version one from AT&T - about $17. Let me know if you guys have any questions or want to see pictures (*waits*).
