I'm 6'-0" 170 lbs with a relatively athletic (but not jacked by any means) build. The material and construction of these seem good through a couple months of use but the proportions (I bought size medium) don't seem to fit my body as well as I'd like. The length is good but they are quite loose at the ankles, calf, knee, and quads so they don't hug my legs very well which is annoying when wearing them as a base layer. They fit much closer to what I'd expect around the butt however the waistband seems to be just a bit too low since they always seems to want to slide down my butt if I'm bending down to pick something up.I think these would be best suited for someone with a slightly larger build, but just know that you may have to pull them up your waist a bit higher than normal to keep our butt covered when bending down. Other than that the construction seems good and these have held up really well for me that last couple months.
