Jeans in winter... ack. If there's the LEAST bit of moisture they suck it up and make you that much colder! Same with cotton sweatpants and hoodies... I'll stick with layered polarfleece (wind resistant kind) and wool, thanks.
Of course, I just realized in Grand Prairie you pretty well don't HAVE any moisture in the air in winter, but I grew up in BC and cotton's a huge no-no.
I like your balaclava idea though.
