Nice jacket, but could be better.
I really like Sombrio shorts and jerseys, so I had high hopes for this jacket as a riding-specific jacket. It is a good jacket with great waterproofing, but a couple things could be better thought-out:
The armpit vents follow the contour of your pit, so that unless you are reaching above your head the vents remain largely closed. However when riding they should open up enough to be useful.
The interior fabric feels a bit clammy compared with some of the 'dry touch' stuff out there in winter outerwear. Otherwise, nice piece - great zips with tight tolerances, etc.
