Consider having the knee armor sewed in
I brought my ce knee armor and pants to a alteration shop to have them sewn in. The shop created pockets in the knee area to slip the armor in to.
For me it is more comfotable on long multi-day adventures as it eliminates the pain of elastic on skin.
Adventure feeds my soul, without it I would wilt
