Love the styling and fit of the jersey but I would definitely recommend a base layer underneath on colder or windy days. As usual with Castelli go up one size larger than normal. I used to be a pearl izumi fan, but I find myself buying castelli more often now.
This is a well constructed beanie with attention to detail and best of all it keeps me warm and doesn't itch. Another bonus is that you'll probably one of the only or few around town wearing it because Discrete is a new company and not played out like most of the other companies out there.
Bar none this is the best jacket I've ever owned! Hiking Rainier this past summer I loaned this jacket to a buddy on the trip who forgot his hardshell, we got caught in a blizzard with 50mph winds and he was totally warm using this jacket as his outer layer. The Polartec Powershield fabric is great because it's windproof and highly water resistant. This is my everyday jacket around town and also works for a good majority of the days in the mountains.
