Prevention is better than the cure!
Plus Dye pants have saved my two veg on two occasions now well worth every penny, your knees and elbows may sting but your boys need help protect them
knee pads in case I have to do my shoe laces up and Elbow pads cos you can tuck in you Marlboro soft pack in the top, for those sneaky smoke breaks when playing at the back
If you're doing it stupidly then yes, you might be checked, but personally I've never seen anyone get checked for layers, and I'm sure I've seen a couple people wear two sets of pads.
