I bought this tri-suit because I wanted more sun protection on my shoulders than my sleeveless models. I bought Zone3 because I knew the size from my other suits. And this model was on sale.
The material is thicker and more supportive than my sleeveless suits. The Small is snug without feeling chest squeeze, basically an ideal fit for me (5'8", 137lbs). I've only used it in one sprint tri and had no chafing (salt water swim), and sufficient seat padding for a short race. My pool swim times are slightly better in this suit than any other. Not much, a couple seconds per hundred, but it seems consistent, and the outer texture is noticeably slicker than other suits I have worn. It also looks very good, nice colors without being garish. I will buy another.
