Anyone ever had experience beefing up a solitude jacket with base-layers, insulation layers to pair with sanctuary bibs? I got an amazing deal on a pair of sanctuary bibs and a almost NWOT solitude jacket for a great price. Was planning on looking for a Sanctuary jacket and Solitude bibs to go with those. But then I thought I might be able to get away with the solitude jacket if I had the right base layers. (i.e. fuse + Klamath + vest) Open to comments and/suggestions.
