I was given one of these to try by the golf shop I frequent. I cant comment on the "ION" part of the glove because I didnt notice any difference...no as to the glove itself...I LOVED it..I have always used FJ gloves and liked them very much...the Cally glove seemed to fit my hand better..the back breathed great...I only used it one round so cant really comment on durabilty yet but it seems to hold up...all in all I will use it again...and I am not a Cally guy...I dislike them only slight less than Taylor Turds...
