SONY XPERIA XZ2 Case, CNC Aircraft Metal Bumper Cases, Aluminum Alloy Bumper Frame for Xperia XZ2 5.7’’(Black)

Fits perfect. Not a hard plastic but not really soft, does the job and fits great

With the XZ2 having a curved and very slippery back its gonna end up on the floor all the time with only these bumpers on it. they offer good protection for the edges of the phone but I dont think that is really enough
