It's not about safety with these fools. It's about looking bad-*** with the other fools at Timmies. However with those fools the one-piece or two-piece zippered together leathers do serve a most useful purpose. When they eventually do go down, the leather is very good at containing the jellied flesh and shattered bones for easier clean-up by the meat wagon people.
Certainly you are not suggesting that wearing leathers in ANY situation is anything but good sense are you?
