Everyone and their mother knows the Midwest (as well as other parts of the United States) have been in the grips of a polar vortex. -20, -30, -40, -50 temps with windchill. I work outside for a living so you can imagine the severe cold weighs on me - and my body. Among other things (layering, socks, footwear), here's three items I wouldn't be caught dead without. Or I might be dead. Or at least frostbitten.
1.) Thermos. This was my Grampa Ircink's. It's old. Brother Jason gave it to me for Christmas. Filled this mofo at about 10:25 am with hot coffee. Had a cup when I got home at 5:15 pm. As hot as if it were freshly made.
2.) Military arctic gloves. Used. Deerskin leather. Insulated. $10 at the Milwaukee Sport Show a couple years ago.
3.) Thick wool pants. $20 on Ebay. Used them for a theater costume. Suspenders optional. Doesn't stay wet and dries quickly.
BONUS: The beard. Well - it can't hurt. Keeps my face warm during bowhunting, in -30 degree windchill and it's convenient for potential acting gigs.
I would add a good hand cream like Udder or No Crack for the wear & tear on your fingers (splitting, cracked skin). OK - go outside in the -40 temps & have fun!
