Typical thick rubber that you find at your local grocery store. The lube is USELESS as well as the "flavored" condom. The smell of the lube is repulsive (strawberry) and its lubrication ends just as fast as the partners enthusiasm.
I'm still experimenting but I only bought these because they were cheap and I wanted to experiment. Maby they are good for some, but I think most are too thick. They never broke on me though.
