I always wear snowmobile bibs and jacket. It is much lighter and warmer than Carhart or work type clothes. It is water proof breathes well and overall very warm with out being heavy. One more important aspect of them they will regulate your body temperature as well as the material reacts to your body heat and won’t make you sweat to death once you get too warm. Even if it does warm up too much they have zippers that open up sections of it to cool you down with out having to peel layers off. Usually around arm pits and back. The cheaper puffy ones can be a litte too bulky but the more expensive kind for snow cross is well worth the money, warm thin and light weight. I have fished in the teens way too many times in the past, If you are dumb enough to fish with 2" of snow on the deck (like I am) you will apreciate warm clothes. (The kind of weather where you have to shake the end of the pole in the water every 10 minutes to melt the ice off your eyelets. And you have to flip a coin to see who has to reach in and get the bait out of the livewell when you forgot the net.)
