Back Protector and/or Chest Protector On The Street - Anyone Do It?

This?

It seems like a decent protection under a jacket but would seem bulky.

What makes me rage is when I see people wearing a similar version of it, just over a t-shirt

Bro just man up and be in a t-shirt of you’re trying to protect your body wear a damn jacket. :banghead

I hold more respect for people that wear no gear at all than the people that pick and chose. Tshirt and gloves? Who are you kidding? Jacket and no gloves and sneakers? really?
