I've always wanted to get something like those. After I got hit by a truck my mom bought me a nice armored jacket with good ventilation. I left it back home with my beemer when I moved to Oz though. It's gets pretty hot here, so the mesh stuff may be better. Also, while in Spain one summer I saw a hot chick wearing the mesh gear and leather pants. She was riding some sport bike, but damn was she hot! Maybe I should get that gear for my wife.
