Familiarity: I've used it several times
My first jersey I purchased was too small- upgraded to XXL. Length is great and the shoulders don't bunch up. The Windstop fabric lives up to it's name and the high collar seals int he warmth. When pushing intervals, opening the top about 4 inches is enough to get some airflow and keep the engine running at full speed.
