I hope I can help with a size chart. I'm a 5'8" male and weigh 165 pounds. A size 51 fits me perfectly. When I placed an order I was initially concerned that the sleeves would be too long (I'm 32-33) but they came about 2" above my ankles and right where I wanted them to end. While the material was surprisingly good for its price, be wary of the zipper (good advice for other men's ranges too) which is quite flimsy. Overall very happy with my purchase.
