My knee armor is velcroed on to my jumpsuit for both and , but only to prevent the knee armor from slipping down. I need straps to stop it from popping off.
I use to velcro my straps onto the knee armor, but the problem with that was the velcro kept coming loose. So now I use snaps to hold the straps on (I use this method on both costumes.) But the straps for my run on the outside of my jumpsuit while the straps for my run on the inside.
