When you buy a pair of Carhartts, you usually are buying a hybrid work/casual pant and you do get that here. The material is super bomber as it does not stretch very much but can still take a beating so work or play these will hold up but make sure the fit is right from the start.
Speaking of fit, things are a bit weird here as I did label them True to Size but I'm kind of balancing out a few fit aspects. I bought a 34x32 size for me as I'm 5' 11", 183lbs with a waist of around 33 and an inseam of 31.5". The size is right, but the cut of the legs are weird as the the waist is just a hair big which I like, the length is slightly long so good there two, but the upper leg is cut a little less relaxed than the lower leg and this is a bit of an issue as my skier legs end up being a bit tight on the top of the inseam yet loose at the bottom. I'm thinking that Carhartt is starting to go toward the more casual wear of jean as most fashion jeans have legs that fit this way.
A good jean for sure as it is something that I can work and chill in, but I'd look elsewhere if your upper legs are more than a bit bulky.
