Tar HeelDevin_GmitterRMH49Reading reviews about the FJ Lisle Pencil Stripe, several contributors said they run about a size larger. I'm 5'6" 160 lbs. No problem with a medium? You would 100% need a small.
Devin always says get a small. He likes the Euro look..... #nailedit. Small in the regular cut, medium in athletic, and medium in outer layering pieces for me!
