After reading many reviews I bought a pair of these pants. When they arrived the first thing I noticed was the weight of the package. The pants are heavy, and that is a good thing. If you are considering buying them, it probably isn't because you want to wear them in Hawaii. Many prior reviews discuss fit issues. IMHO, there are three dimensions that you should know when buying pants: the waist, the inseam, and the outseam. Most online sites provide only the waist and inseam. I think many of the issues that people report with these pants are perhaps due to a longer outseam. The outseam, in case you are not familiar with this term, is the measurement from the top of the waistband to the bottom of the leg. As the outseam increases, all else the same, the pant either sits higher and higher on your waist, or the crotch migrates to your knees. I measured the inseam and it is exactly what the manufacturer says it is. I compared the outseam to that of some other jeans (Levi 505, and 506) that I own. The outseam of these Carhartt pants is about an inch longer. If you then wear them an inch higher on your waist, the length should be fine. However, if like me you suffer from MSD (midsection bulge or CBB chronic beer belly), a common problem, then your waistline may increase rapidly the higher on your waist you wear the pant. I you buy your normal waist size, this forces you to wear it lower, and then makes the pants seem too long. May I suggest that you measure your "waistline" when wearing pants that fit, and then measure it an inch higher. If those measurements differ, you may want to go with one of two strategies. The first would be to buy your normal waist and take the length an inch less than you normally do. My pants are slightly long, but since 30" is the shortest inseam available, I really didn't have any option. Alternatively, choose your normal inseam and increase the waist size so the pant can sit comfortably a bit higher on your waist. I hope the information on the fit is useful to you.
The pants appear to be sturdy, well constructed, and I get the sense that they will last for a long time. As others have noted, the legs are roomy. I don't particularly enjoy the sausage casing look. There are several other features worth pointing out. The front pockets are fairly deep, which is a great thing if you don't like losing things like keys and change from your pockets. There are seven belt loops. More and more often pants are being made with only five. The added warmth of the flannel is evident but not overwhelming, and what I wanted. There are some smaller side pockets in the leg. An iPhone 4, 5, or SE, even with a case, and an iPod fit; I doubt that a Samsung or iPhone 6 would fit. These are not elegant pants by any means, but they meet my needs very nicely.
