WI had -17 this am. I drive school bus, those big metal boxes don't warm up fast! You are never too old for snow pants! Layers, layers, layers! I wear a hat with a fleece hood over the top, & sometimes a headband under). Keep on dry sox if possible, change often during the day, if you spend alot of time outside. Start the day with boots on a boot dryer (it heats them nicely). Remember to drink lots of fluids, it helps keep your lips from chapping as easily. Go inside & warm up as often as possible, but unbundle when you do, so you don't sweat up, or you'll be colder on the next round.
