this be a replacement pair for the original speedo swim glove that have a zipper on the side . the other pair I use for over five year in a morning water work-out class three day a week . the glove really help to build the back and arm muscle . these new one have a velcro closure instead of a zipper fit but stay on firmly throughout the class . I definitely get my money 's worth on the last pair and if these last near as long I 'll be thrill .
