Two-piece outfit is this season's coolest combo. Timeless look in the smooth to the touch material for your little one. With a style and comfort wrapped in one outfit, your baby will enjoy his new world of exploration from morning to night. Practical and adorable, our classic set is designed and crafted to withstand marvelous everyday activities. With thermoregulating properties, both pieces trap warm air and keep your babies snug even on the coldest days or nights, holding in heat next to the body. Made from Merino wool, the breathable garments naturally absorb and release moisture vapor from the skin toward the outside of the fabric in order to evaporate quicker. Many kids like to wear them under, over, between layers, or with no layering at all.
