I wear layers of stuff good long johns and a filson wool vest and carhartt fr jacket.. warmer than standard carhartt. I got my gear before a job in prudohe bay Ak. they sell good stuff in Alaska. hunting I wear a good old army field jacket with issue liner. been wearing that jacket for 30 years. I love the draw string around the waist, makes a big diff. fr jacket has it too. use wool silk or polly pro for layers;
feet are tough to keep warm. best I found is schnaes pac boots (usa made) with wool sock liners. take dry socks and change socks every 2 hrs or so. also whites dry foot work pretty well.
