I had to do some extra work to make these fit. You NEED to strap these to a belt or they will fall down. NEED. So measure from where you wear your belt and make sure it is tight enough to hold these up. I ended up attaching these to my breastplate with a d ring and a clip that i added on. I wear them tight at the thigh and loose behind the knee to get the most movement without alot of up and down movement on the Armour.
