yeah I wear a one piece
Ok, Its a one piece and I love it. I got the size large in lime and I am so psyched. It fits a bit on the big side. I have skied in it twice and it is super warm, it vents well and I am thinking I wont have any issues with snow in the pants on powder days. Most people cannot tell it is a one piece because the top doubles over the bottom. Only down side is, it maybe to warm.
