Very useful item for bone hardening and martial arts if you don't want to permanently damage your shin bone or knees by accident. They also stop you from flinching when you are kicked in the knee or shin.

I also found the knee protection to be the most effective, I have not seen any knee protection that comes close to this, I can really take some hard hits to my knees wearing these. They wrap around my knees like a shield and don't shift my kneecaps upon impact like other padding does.

Amazing protection considering how thin and flexible the pads are. Helps a lot with preventing injuries, while remaining 100% concealable.
