After using the 0-3 month sleeping bag for the baby's first weeks, the Premiers Moments lightweight sleeping bag that evolves 3-6 months is the perfect sleeping bag for periods of high heat. It accompanies baby growth by adjusting to their size (60 cm or 75 cm) thanks to the two press buttons located at the back of the sleeping bag. The space for baby's arms can also be adjusted with two press buttons. The full opening of the sleeping bag (also called swaddle), thanks to its secure zip, makes baby handling much easier. Its outer fabric and lining are made of jersey and made of 100% organic cotton (GOTS certified fabric), which prevents any risk of irritation to fragile baby skin (Oeko-Tex label).
