So i’ve finally decided to invest in some good layering stuff. I hunt public land, walk a mile plus to get to the spots i like. In the warm and cold season i wear shorts and a tshirt for the walk in. I then layer up and get in the tree or blind. I bought some expensive thermals from bass pro a few years back, level 4 something, $ 100 for the top, and $ 100 for the bottoms. Maybe i do it wrong or there are more layers needed, but I still get cold with those underneath their insulated bibs and jacket.

Can someone school me on proper layering, with names of suggested articles of clothing? Thanks!
