Does no one make normal,non-TPU silicone cases anymore?

i've been looking around for DAYS to find a normal, silicone case for my new 640. Just a rubber case. No TPU, no hard plastic, just normal silicone. Is that too much to ask? It seems no one makes these cases anymore for any phone. I remember these types of cases being super popular back in the days of the iPhone 4 and iPod touch 4G. If anyone can find some, please link me them.
