Yup once I learned how to layer with wool I very rarely use my heavy insulated bibs and jacket. It has to be windy and down in the 20's to bring those out. Most my hunting is done with a wicking base layer and a wool layer under my regular hunting clothes. Wool layer thickness depends on the temp. I also use a light weight puffy jacket that is made to be quiet.
Outstanding stuff. I pair it with fleece a lot of times and I couldn't tell you the last time I wore any of my heavy insulated stuff. Nice also to keep the bulk down.
