The pants are good quality and fit well. My son is 5’6” and 145lbs. I bough Men’s M and they fit well, like baseball pants should.

I am so happy we were able to find this company for all of our baseball apparel needs as my child has very long legs but a small waist (he is 5’7 - typically he wears a boys 14/16 he is 12 YO) their baseball pants are great as well as being great quality and long enough for my child to wear the longer pants but overall the quality is just amazing for the price point.
