As much as you may wish your tot would hibernate just a little, her energy does not dwindle when the weather cools off. The Columbia Toddler Girls' Glacial Leggings are constructed with featherweight microfleece, keeping her warm while she's playing outside and maintaining breathability when it's time to come in for a nap. The stretchy fabric allows her to walk and tumble uninhibited, and the ankle-length inseam protects the soft skin on her knees while she's crawling.
