Let's talk about layering. Considering a bib this year vs. pants. So, I've always worn insulated snowboard pants. Usually a synthetic long underwear under there depending upon outside temp as a base layer but that's pretty much it. Considering switching or at least trying a setup with a bib this year and I'm wondering what layers people are using? Most of the bibs I see are not insulated but are just an outer layer meant to be paired with layers, correct? What do people wear under their bib?
