For Smartphone my son I bought this bag. It is relatively tight - as regards the amount, is absolutely no room for maneuver. The material is very valuable and protects the smartphone really. It has survived several falls, where the SP is generally very stable. Even the Velcro makes a good impression. Visually see the shell also not bad, kept relatively simple, fits them perfectly to SP.
I highly recommend this sleeve to anyone own a Sony Xperia SP, of a "sock" type envelope want (ie no FlipCase, etc.).
