I am 5' 11 , 165 lbs and I ordered a large which is just right. It is snug which is good for biking. I use it for riding in cold weather only. It's good down to about 35 degrees. Any colder than that, I'm on the indoor bike. The yellow part is the windbreaker and the black part allows in some air which keeps me from sweating. I use a heavy sweatshirt under it on the colder days. I have not used it in the rain. It seems to be of good quality and I am very pleased with it. It allows me to have more time in the saddle..
