I have a question…………..I am looking for a wookie type under quilt similar to what warbonnet makes but with the insulated section wider. I know the sld trail winder comes in several different configurations ( asym, non asym, asym with broad shoulders etc). I really like the sld design but would like down instead of synthetic insulation. Any suggestions? I could go the diy route, but I really dont like working with down. Any one do custom work? Thx for the help!
