@goosehd I should have checked before asking, sorry. Looks like the numbers of the TypeIII Large line up more with the Medium in this jacket and since I'll be dressing lighter underneath, I think the Medium is the right call here. 6' 1" and 165lb. Thanks for the quick reply.

Guessing this will fit me the exact same as the Modified Type III? Im a 40 in that jacket.

thanks
