It's probably similar to Arc'teryx and their Veilance line. For the pieces with mainline counterparts the "technology" is the same. So the same water repellency and the same amount of coreloft filling, etc but with a different aesthetic, higher price tag and different fit. Their may be a difference in the quality in construction but I wouldn't hold it much higher. Regular Carhartt is supposed to be workwear so it should be tough, and regular Arc'teryx is supposed to be quality hiking gear so it's going to function for sure. I'd really say you're just paying for a different aesthetic. It is fashion after all.
