in my late 40s, I have always noticed that being cold didnt agree with my leg muscles and such. Same with XC skiing, so I tend to be on the conservative side for leg warmth and make sure I have more than less, as the downside of not getting it right is pretty evident for me--stiff, achey, slow etc.
