I've used a couple of different sets of pads for kneeling, depending on the costume. One set were a pair of neoprene knee pads that I bought decades ago for doing aikido, but I've not seen them on the market recently. They provided a lot of padding, but were black on the outside and red on the inside, so did not work with all costumes. More recently I got https://www.amazon.com/dp/B0C5GKM52V which just barely fit me (I'm male with fairly thin legs—these would not fit most adult Americans, who have thicker legs than me). The padding in them was adequate. I would not use knee pads that have hard shells (intended for protecting knees from impact in some sports), as they restrict movement and look awful under costumes.
