My personal fitness regime includes 2-3 days of Cardio-Kickboxing, and I'm always looking for the "right" pair of pants that will fit well, wick moisture, and stay put.  These pants do see to fit the bill on each count.  They fit well - but they are very snug- to the point where they need a little getting used to.  They "wear" a little rigid - it's a more tightly woven material; but overall, that's not bad.  The waistband is the only real drawback in terms of fit.  The waistband is very thin, and after only two wears, I don't think it will hold up very well, without getting twisted out of shape.
