Love these pants! I've been a dedicated Carhartt wearer for years, and these pants are definitely an upgrade. They are far more comfortable and seem about as durable if not more so than the double-fronted Carhartts I've been wearing, and are only marginally more expensive. Excellent pants for hiking, working with animals and plants, biking, kayaking, etc, etc, etc. The weave is durable but rather light for a cotton duck, so they are great in the Deep Southern summers compared to some other pants but don't fare so well in the winter.
Like other posters have noted, I intentionally bought a size up and they were just the right size. I usually wear 38x32, but I bought 40x34 and they fit perfectly.
