I've owned the MB UL Down Inner jacket for over two years and absolutely love this thing. Mine has snap closure system, and comes without the new pockets and zipper, and yet, I love it.
By itself, I am perfectly comfortable down to 40 in this jacket. Add a rain shell, I go lower. Add my micropuff vest, and I'm really happy in all of the 3 season conditions I find myself in.
Love it, love it, love it. The down makes me a little nervous in wet weather, and I wouldn't mind trading it in for the newer zipper/hand warmer model. But really, this is my go-to jacket on every trip.
