micoach is all you need to get the results you want.
These are lovely tracksuit pants that glide against the skin. I initially bought the XS (the size I normally wear) but found them fairly snug around the calf and knees and knew I couldn't cycle in them. The S are cool and baggy and a little loose around the tummy, but not enough for me to worry about. If you want to wear them to walk in - get your normal size. If you're planning on doing a few lunges / cycling in them, maybe go up a size!
