Aero for cold winters

Great choice! The Irvin is my go-to once we get into winter. I've had it for more than six years, it gets loads of wear and looks better with every passing year. You'll have to resign yourself to the cuffs getting a bit bald with wear, but that's just part of the look. The sleeve shape is spot on, you need the space at the top of them for ease of movement and to allow circulation of air. I would tend to go with a size up from your usual one, it looks better imho.
