Now, investing in a season's pass has the capacity to be rendered moot when you try to ski on a cold, January day without a pair of warm baselayers. However, the Under Armour Women's Base 3.0 Leggings ensure not only that you get the most bang out of your buck, but you stay toasty-warm from first chair till last. Moreover, these midweight tights are the ideal base layer for skiing or snowshoeing in cool, crispy winter weather. The Base 3.0 fabric features a textured interior that traps heat more effectively than a mere knit, and it also helps wick moisture quickly and efficiently for complete comfort when you're working hard.
