Give her the perfect base for every season with the Cuddl Duds Girl's Lightweight Active Base Layer Set. This 2-piece thermal set for girls includes a long sleeve shirt and pull-on leggings, both made from soft, breathable, and stretchy fabric that moves with her. Ideal for layering or wearing on its own, this set offers year-round comfort without the bulk. At 170 GSM, it's lighter and more breathable than our heavyweight thermals - great for mild weather, indoor comfort, or days filled with play. The tag-free design helps prevent irritation, while the moisture-wicking performance fabric helps her stay dry and fresh through school, activities, and everything in between. With a close-to-the-body fit, 4-way stretch, and built-in UV protection, it's a dependable staple for active kids on the go.
