I'm looking to spend around 50 dollars on a pair of thai gloves, but i don't know which brand and size to get. I heard windy and twins are good for the price? is this true? I want the gloves for sparring, so i don't know if i should get 14 or 16oz gloves, my hands are pretty big btw. Plus if anyone can recommend a good site to buy them at, that would be great thanks!
