The set is made from high-quality "kulir" fabric – a natural cotton material that's excellent at air circulation, allows the skin to breathe, and doesn't cause irritation. The fabric is pleasant to the touch, soft, and at the same time durable, which is especially important for children's clothing. The bodysuit conveniently fastens between the legs, providing easy access for diaper changes, and the short sleeves add comfort on hot days. The shorts feature a soft elastic waistband that doesn't put pressure on the baby's tummy.
