I'm guessing you mean sparring gear. I use a shock doctor nut cup and some compression shorts. I got a twins headgear from nine dragon martial arts and I love it. Mouthguard is kind of a personal thing.
Many people will point you towards a custom guard, but it all depends on what your teeth are worth to you. I personally just use a common boil and bite until I can afford a custom. As for custom guards I hear pythonguards makes nice ones.
