goddamn. if this was a medium i would buy it off you right now
edit: flight jackets are supposed to fit snug, and it was a summer piece, so are you maybe layering a hoodie and wearing it wrong? no offense...
have you even owned this piece? You shouldn't be commenting on stuff you don't know about (no offense). i have this, im a true medium and this literally runs one size smaller.
i dont own this jacket specifically, but a general rule for flight jackets is size up if u want a "normal", looser fit. so yeah it should seem
to run a size smaller. Im a medium in most cases, but id still go medium with this piece so that it fits how a flight jacket is supposed to.
