What can I say - they're Carhartts. These have a feature in the right front pocket that accommodates carrying a knife - very nice. These have rear patch pockets that are placed high on the pant - very nice. This allows one to carry stuff in the rear pockets and not worry about sitting down/sitting on whatever you have in your hip pockets - much more comfortable.
The fabric is comfortable (cotton). These launder well - no wrinkles. I really like the cut of these pants - fit me in the seat/upper legs (other styles of Carhartts have too much fabric in the seat - too baggy!). I really like that I have found Carhartts that fit me!
