These look interesting. I just wear fleece pants ( have a few pairs that have for hiking in Fall and ice fishing in winter) with a pair of waterproof/breathable rain pants over top. Never get cold. Upper body is long sleeve Underarmour cold gear shirt, fleece pullover and a waterproof/breathable jacket. No bulk and stay warm.
some guys use a cart cover when temps drop into low 40's and high 30's. I actually prefer to walk as it jeeps body heat up more.
