<< Polyurethanes are supposed to be super strong, super thin, and transfer heat better than latex.
Also good for people with latex allergies. >>
Polyurethanes are great. Way better then Latex. No odor. Transfer's heat better (think Artic Silver gear heads...). I just wish they came in larger sizes besides regular. Also, they are more expensive and are not as proven as the tried and true latex condom's.
