I would recommend MMA gloves for MMA. I don't know what you're going to do tomorrow. You can probably by all the equipment you need through your school.
be easy, don't be tense when you fight/train, stop worrying about it. if u go to a decent school they will provide you with examples and prices.
typical mma gloves are 4 ounces (1/4 or a pound) the prices can range between 50 and 100 dollars. go in shirt n shorts. you're gonna work out and possibly roll/wrestle tomorrow
