I have the UL Down Inner and the Alpine Light jacket. I wanted to get my wife a jacket that had about the same amount of loft as the Alpine Light (she gets cold!), so I got her the Women's.
So the jacket came today… and although I didn't have time to let it loft very long, straight out of the box it looked like it had no where close to the loft of the Men's Alpine Light. (I ordered three to get the right fit – so I don't think it's an "underfill" issue). The loft seems closer to my UL Down Inner.
So… is it the diamond baffling that keeps the loft down? Do the MB jackets just have less loft in the women's apparel?
