Haven't even worn it yet- but I was very impressed with the weight, softness and quality of this jacket. I'm 5'7" 135lb and based on the sizing chart I was almost reluctant to order a Medium as it said it was for chest sizes 35-37inches- thinking it might be too small. I like a tight race fit and have a 37" chest so I went for it. Wow- it's huge. big and baggy in the stomach area, flappy arms, even around the neck it's open for me. Rather saddened, as it's such a magnificent jacket at a great RealCyclist price- but I just can't imagine wearing it without it flapping all over the place.
