This zip-up swaddle is TOG rated for warmth to keep a baby snug and securely swaddled without the need for complicated wrapping from day one.
Being TOG-rated means that the 0.2 TOG can be used on its own from room temperatures 24℃ / 75℉ + with no blankets in the bassinet or cot to make this a safe sleep option for a newborn or baby.
