My wife bought me bibs and a jacket. The jacket has to be carried in. The clothes work well but no better than my usual 5 layers. You can cut down on the layers. However at 20 F with a wind I still got cold in spots. A few hand-warmers in strategic spots did the trick. Good underlayment, wool or fleece mid-layer, a vest and the bibs and jacket are about as good as it gets. A plus is that they are waterproof. So a drizzle at 39 with just 2 under layers will make you feel like toast. Two tips, if you sweat walking in they keep that moisture on you and you're going to get cold. Secondly zip and button the whole outfit as the working principle is it keeps the heat from your body sealed. They also tend to get a little stiff when its below 20 F. A very good tool especially for cold damp weather.
