Familiarity: I've used it several times
I'm not sure what to call this garment. It wears like a jersey but protects like a jacket. The double zippers is a little odd, but it is nice to open the front and still be protected. I've done about 10-12 rides in some varied conditions. I've worn this with no baselayer in the mid thirties on a very windy day and was quite comfortable. Hovering around 40 with passing showers it kept me dry, well at least my body, and warm. Started out at 30F and finished several hours later at 50F and the jersey was perfect. For me I'd say with a light baselayer on a dry day this would be good down to about 29. I'm 6'1" and 165 and the large fit me beautifully. Highly recommend!
