Pretty sure that's not what kneepads are for

Well, if they'll approve another manufacturer for procurement, I'd suggest 5.11 tactical. Their ems pants are available with kneepad pockets and they've already been teflon treated. http://www.511tactical.com/mens-ems-pant.html

Also, if you're going to retrofit your existing pants, I do like the kneepads 5.11 makes. Relatively thin neoprene(3/8") with a nylon backing, so only one side grips the pad pocket, eliminates bunching. http://www.511tactical.com/kneepads-pair.html

They won't allow different types, the trousers are branded with the organisation name - I have two different types of 5.11 trousers for other work and that's where I've filched the kneepads from that I'll retrofit I just need to sort out the sewing as and when I have the time.
