What size is (50) in Easton Pants

[hellkitty 0]

I just got some pants and the seller claimed they were a small. But when i got them they feel like a med or large and on the tag says (50). I thought a 50 was either a med or small. Can anyone confirm. I do not know which pants they because they are pro stock.
