Neoprene is the type of material used for diving wetsuits. It retains and reflects body heat even when wet. This is a good property. Some people are allergic to neoprene though and may get a red blistery rash.
I think that mask looks awesome.
I remember one time I was biking (pedal bike) and wearing a ski mask and foam bike helmet in Jan. A woman blocked me with her car and tried to hit me. I dodged the car, pulled the mask and said, Hey Mrs. XXXX whats going on? She was shocked that I was her yard boy and not some cat burglar. Some people are just ignorant about biking and winter clothes.
