I'm sure sitka gear does great, but it alone don't do it. you need to figure out layering with the right materials. also I take the hot hands and put one over my heart andsometimes in my Mid layer pockets then cover them with my heavy coat or bibs. same as for feet the toe warmers between two layers of good socks kept my feet good in 20 deg while duck hunting.

I believe that this is a practical world and that I can count only on what I earn. Therefore I believe in work, hard work. -George Petrie (1945)
