Corp Cord Jacket and pants question not for sale

hey, i just got the corp cord jacket, and i was gonna get the cord supply pants with it, but the dood i was gonna get them from misplaced them. o well, so any way, i was wondering if i should just buy a pair of those or maybe get the Rig pants which is 10,000 water proof and cord color but not cord. so anybody who has had the cord pants i was wondering how do they fit, because it says on the site that there a regular/slim fit and the Rigs are loose fit, im 6'3 and would get the xl for both. i want my pants to be big, so do you think an xl on the supply would be big enough? any recomendation? i also was wondering if the Rig pants in cord color are exactly the same color as the jacket? they look a little lighter on the website.
