I have the Cannondale Morphis jacket (mine is a few years old, but it looks the same as this year's in style...just different colors).

I LOVE it. It has the raglan zips, so not only can you remove the sleeves, you can unzip them a bit and treat them like pit zips...which I do often in the winter. There is mesh on the upper part of the vest (covered by the sleeves when they are on as they are all one piece...like a bolero), so there is no billowing.

It's not as light weight as the whisper jacket, but it's so versatile that I find I use it in TONS of situations.
