Am_Fear_Liath_Mor, I think I will still give a try to the vintage fishtail parker (and come to think of it, a Lambretta scooter may be a nice bug-out vehicle in traffic). My rational behind this is that since the upper legs produce a lot of warm air, I'm figuring that with sized-up wool pants holded by suspenders (instead of belt) would allow for this warm air to flow to the core and that the fishtail would be lower than a powder skirt, with the same idea of allowing this warm air to flow...
