these probably would not be the best choice for spar , after all they be pretty cheap price wise . have say that , they really be wonderful quality for the price and if it be all someone could afford for spar it still beat the hell out of the alternative in the same price range . I buy the 12 oz to use on a punch bag . they work great . this be after return some cheap century glove , which be total crap . for the price , Everlast make by far the best product . these glove be really pretty damn nice consider the price , and I be glad I get they .
