I'm not 5' 10” 185 lbs, and decided to get the XXL so I could fit a down vest under it, and I chose well, as it gave me some leeway for additional warmth when riding my bike. I've worn it several time now with nothing under it, and it's not excessively large, and still works well keeping the wind from cooling me too much. Zipper seems sturdy, and an inner sleeve between you and the zipper, for additional warmth. I'm happy with my purchase and would buy again from this seller.
