New favorite winter training jacket. Handles wide range in temperature and training efforts. Zippered side vents are awesome for climbing. Not a wet weather jacket but is uber-functional otherwise. I bought couple more once I saw how well they function. Zippers seem very durable.
This jacket blocks the wind very well and keeps my chest and arms warm while still venting heat and sweat sufficiently. I wear a merino wool base layer and the combo is very good from upper 30s to upper 40s. I don't ride when it's much colder. The size chart is fairly accurate. This jacket runs small. I am 5'5' 149 lbs 40 chest, 30 waist and the large fit just right over my base layer - snug but not too tight with sleeves just an inch longer than I like but body just right.
Finally managed to get out on a ride with the jersey after the snow cleared. It fits really well though the main design goal is comfort rather than aero or race-fitness. Be aware, it's well insulated but not windprooof--a windbreaker/jacket will be necessary on those gustier days. An insulated baselayer will help for those even colder days (30s-low 40s F/0-6 C). Pockets are well-sized and secure--I was able to fit all my usual contents with no trouble. And the color (Red Dahlia) really stands out.
My only criticism: the shoulders are a little narrow--I'm a pretty averagely proportioned guy and in all other respects, the recommended size (M) fit me perfectly. But the shoulders are probably a 1/2" narrower than I'd like. It's not a deal breaker by any stretch and didn't impede my ride in any way so I'm still more than happy to recommend the jersey. But something to keep in mind for those who have wide shoulders for their height.
