I be a avid participant in water aerobic class , and use to use the glove that my fitness center provide . but I decide to buy my own pair recently , and have find a couple issue with this particular brand : 1 -rrb- they run a bit larger than expect . I buy a medium , and they be a bit too big for I . 2 -rrb- they do not stay fasten with the velcro ! I find myself constantly have to stop what I be do to reattach the velcro wristband . they seem to be make well as far as the material use for the actual glove itself ; sturdy and provide good resistance in the water . I only wish the velcro wristband stay attach during my exercise . it may have to do with the fact that again , these be a bit big for my hand , and I have to pull the velcro strap over as far as it go to attach they .
