Our 2-piece set, including a pullover sweater and jogger pants, is made from French Terry knit with rib cuff material. With a blend of 95% cotton and 5% spandex, our baby, toddler, and kids' clothing is designed for everyday wear, providing both comfort and durability. We recommend washing this set with cold water and similar colors, and either hanging or laying it flat to dry. You can also safely machine dry this set on low heat without worrying about shrinkage. For best results, use natural detergents and avoid softeners and bleach when caring for our baby clothes, knits, linens, and organic cottons.
