PCMICROSTORE Brand SanDisk Sansa Premium Silicone Skin Kit for e250 e260 e270 e280 - Belt Clip - 15 Inch Sports Armband - LCD Screen Film - 9 Color Options , BLACK
The skin is great.  I looked at many and this is much better quality.  It fits well, and the sansa player is easy to use inside of it.  It came with a belt clip that I don't use and an armband.  Unfortunately the armband is only 15\\" so it could be too short for some people to use.
