Comfortable Reebok tennis or track warmup for male or female. 1980’s original worn less than a dozen times. Tag says XL but I’m a large male and it’s a little small on me (that’s why I didn’t wear it much). 1980’s sizes were smaller than now so I believe it will fit todays medium size individuals. I’m 6’0” and 170 lbs. It’s for anyone smaller than that.
