This is one of the best pieces of cycling clothing I own. It is the perfect thing to wear when the temperature cools down. Normally I would wear a base layer, vest and a jersey and I find that I can skip all of that and just wear this. Sometimes I wear it with a base layer but because it is not skin tight there is air circulation so my temperature comfort stays the same for longer. I love it. It is windproof but has ventilation. I bought the screaming pink and have been told that it is highly visible with I also love.
