The MK Original Mountain Pants are a great idea. Beefy, cotton duck canvas khakis that I can wear when I'm hiking and bouldering down in Palo Duro Canyon, and can dress us with a button-up for the office or a night at the pub? Sounded awesome to me. Make no mistake, these pants are tough. They can take anything you throw at them. Unlike regular cotton twill khakis, these will not rip on crags and rocks on the trail. They are tough and heavy, but breathable. They don't feel as stiff and cardboard-ish like Carhartts. The only issue is sizing. Sizing is a crapshoot, at best. From what I've heard, you must order "true to size". I'm 5'11", 160lbs. I wear between a 30x30 and 30x32, depending on the brand of pants. So the first pair of OMPs I bought, I got a 30x30...and I was high-watering like crazy. So, I exchanged them for a 30x32. These are about 2" too long, and they drag the dirt. I would wear them a LOT more often in social settings (sales calls, meetings with clients, etc) if they weren't so long and baggy. But, they are great trail pants and I pull them on time after time when I head down to the canyon or when working around the house. My advice would be to visit a retailer and try on a few sizes before ordering.
