I have a couple of thin shells that are packable but not as water-resistant as the 7Mesh Resistance will be...fine for mist or a few rain drops here and there. I either start with polypropylene or merino base layer...usually very thin, a thick winter-weight synthetic jersey and then a shell or windproof-front jacket (I have three progressively heavier Specialized Element ones). That covers me from 20-60 degrees Fahrenheit. Actually, above 45, I don't even bother with thin merino base layer. Rain throws this out of whack, hence my latest purchase of two 7Mesh shells. This will enable me to ride in light snow and occasional rain if caught out. With my fat bike and Zwift, I should be in great shape by the time my long rides come up. I'll certainly catch my mountain biking buddies off-guard since they ride much less in the winter. Above 9,000 feet I suffer a bit more than the others. Maybe not any more, thanks to good gear.
