I'm thinking of adding a mid-layer for my Oct-Nov. rifle deer/elk hunts in Idaho. I already have base layers, heavy weight hoody, and puffy. Sometimes the heavy weight hoody is a little on the hot side, so I'm looking for some feedback on some midweight zip-T's. Any experience on the Sitka core midweight and KUIU Peloton 200? Am I better off adding another lightweight shirt over my base layers? Thanks!
