I’m one of the people who do OK in the heat, but cold weather really effects me. My legs and back stiffen up as soon as the cooler weather sets in. Last winter I started wearing thermal pants and tops under everything and it helped tremendously. The stuff is really thin and fits under all my usual clothes without bulking up at all. The tops come in all styles -- long sleeve, short sleeve, no sleeve, crew neck, v-neck, etc. You can buy them on-line at Lands End, J. Crew and places like that or most clothes stores carry them in the winter. If cold weather bothers you, try it out. I’d be curious to know if this works for anyone else.
