If you're in between sizes we suggest you go a size up. Same length as our previous stealth leggings but we have improved the waist, a thicker waist band and made it more tapered, although they may be difficult to get on which will vary with body type they are designed to fit like a glove when on. A higher waist to keep everything tucked in and avoid needing to pull up during workouts. Model is 160cm wearing size S and would usually wear size S.
