I have an athletic build (weight training), so I'm always skeptical when it comes to pant sizes. I usually wear a 34x32 in jeans, knowing ahead of time that the thigh region will most likely be tight. I ordered these in a large, but they were way too big on me (waist/thigh region actually true to size 36). The medium fit more on the snug side, but was more-so what I was looking for in a fit for baseball pants. I can't comment on the durability yet, but the material seems thick and they are comfortable to move around in.
