For me, this jacket is way more versatile than some of the Castelli (both shell and insulated), Gore (Phantom included), and Assos (insulated) jackets I owned over the years.
Oh, BTW, this jacket is not waterproof, but windproof and water-resistant (but I wouldn't consider wearing it if it's raining and you have to be out more than 10 minutes).
