Made from the softest, organic merino wool, this short sleeve bodysuit is both light and stretchy. The suit has a smooth and even surface, but if you look closely at the fabric, you will see that it has a tiny rib structure for flexibility and stretch so your baby can move around and play freely. Merino wool is naturally thermoregulating and breathable, which means this bodysuit can be worn for both playtime and naps throughout the day. The American neckline is perfect for babies and newborns as it offers plenty of room and flexibility whenever you change your young child in and out of the bodysuit. The poppers between the legs also make it easy for you to change your baby.
