When 40* and under, I ususally go with 2 pair of long-johns, pair of medium weight pants, and wool bibs. I then go with one long-john top, turtle neck shirt, button up fleece and then depending on how much cooler it gets I put on a wool sweater or a fleece Sasquatch, or both. All with lacross insulated rubber boots. It I can still move, I slip my ASAT 3D over the top and I' m ready.

Oh yeah, fleece toboggan, neck gaiter and gloves.

It its hot, I wear shorts and tee shirt with my ASAT on top.
