The pants are nice and a Filson tin-product which is always a bonus, but not made in USA. I am also a 33 inch waist and ordered the medium (says up to 34) and if I put even a couple pounds on this winter, which I tend to do following soccer season, these pants will be stretched to their button-popping limit. No way long underwear. I would say order medium if 32 or order large if 34 and above. 33 beware. "Let the boys breathe" feature on pants is awesome especially since you can't wash them!
