I have 3 armor combos that I wear under one of 3 riding pants, these include Bull-It & Draggin' riding jeans, and Rev It riding pants.
Bull-It riding jeans with their armor in the knees and hips. My least favorite since the armor doesn't always line up correctly and can move around in an accident.
Motocross knee protectors with armored shorts. The armor stays in place but for some reason I don't use this combo much even though it functions well and isn't uncomfortable. I got this at a Cycle Gear store, very inexpensive.
Bohn armor for knees and hips. I use this all the time, it's my go too armor. It lines up correctly and seems like it will stay in place much better in an accident than armor that's sitting in the pockets of the pants. I've recently taken the armor out of the Rev It pants and now only use the Bohn.
So after 4 years of riding with armor in the pants Bohn is the winner for me. I run it under a Kevlar jean or riding pants.
