I wanted a pair of winter-ish riding pants and thought these would be perfect. The first thing I have noticed about Club Ride pants (liner shorts and spin pants) is that they ride very low in the back - which is not something I am used to with bike bottoms. I’m 5’6” 130lbs. Athletic build. The medium Spin Tights fit great - length, legs, butt…….except the waist. It was so loose that if I were to wear them riding, they would show (sun burn or chill) half my backside. I returned the medium and bought a small. The fit of the small was “meh”. The length was short, too tight in the thighs and waist line sat really low in the back. I could have kept the mediums if I spent the time to install a drawstring to keep the waist band in place. For the price, I decided neither the small or medium fit well enough to keep.
