(Just in case, here's a bit of silly reasoning - to people accustomed to growing smartphones, a few mm more might not be much ... but I'd like to keep the already-not-sooo-compact compact as compact as possible while gaining a certain degree of trouser pocket capability)
Just as the title says - I am looking for a flip(-down) case for the z1c that does add close to nothing width- and thickness-wise. The few I've seen so far seemed to add at least 6 mm in overall width (feel free to correct me, I didn't have a ruler with me) and quite a bit in thickness, too. Are there any suggestions? Basically, just a plastic shell and a plastic flap with thin piece of microfibre clothe on the inside ... kinda like that.
