Bought this last week, went on my first ride with it today, 3.5 hours. I’ve a 36 inch chest, 34 inch waist and bought small. Size is prefect for me, it looks very small but stretches nicely and doesn’t seem to stress any of the stitching or seams which appears very good quality and will therefore be long lasting. The feel of the material and look is excellent and in my view is significantly better than Le Col or Castelli and for much less money. It’s very comfy to wear. I bought some of Chapeau’s jerseys a few years ago, they were doing some sort of bamboo type material or other.if the quality of this New Jersey is as good as my old jerseys I should get a good 5 years or so out of it. Will definitely be buying more stuff!
