These fit well assuming you know to size up in MK waist by at least 2. I wear a 34-36 in most jeans and got these in 38 and they are comfortable. The cotton/ nylon/ spandex is light and breaths well. I went geocaching in these in high heat and humidity and it was easy to bend, climb, crawl and scoot anywhere I needed to and they dried fast when they got wet. I take off one star however as the pockets are disappointing, described as "Angled, deep drill hand pockets"... I wouldn't say there is much deep about these and in fact they are shallow and don't hold much. If I'm wearing cargo pants I want to be able to carry a lot in them and I found I needed the cargo pockets to hold stuff that would normally fit into the pockets of my jeans.
