what r the 4 little buttons for that comes with the armor vest? anyone know?

 

there the replacement buttons on the spine protector
i have the vest to i wear it and A* knee protectors when i go crusing

 

i have a pair and no one can tell that i wearing them and i feel protected i think there great

 

I had a friend that went down wearin knee pads under his jeans. they didnt do whit for him. as soon as he hit the pavement, they slid down to his ankles. Other than knee pads, I wear all the other gear (ie. jacket, gloves, helmet, thick jeans, riding boots) They sell actual biker jeans, Ive got 3 pairs, and they help alot against road rash.
