This Voksi City North sleeping bag is a premium down-filled stroller footmuff and baby sleeping bag that keeps infants warm through autumn and winter with a unique box construction that blocks drafts. Wool in the back helps regulate temperature and wick moisture while the 80/20 down-and-feather filling and insulating air pockets deliver excellent thermal performance. Soft cotton lining ensures a comfy surface to lie on, and the windproof nylon outer shell with a minimum 8,000 mm water column plus BIONIC-FINISH®ECO water-repellency protects against light rain — use an external rain cover in heavy showers. This stroller bunting bag pairs easily with prams and carriers to provide weather-ready comfort without excess bulk. Always ensure plenty of air around the child's head and supervise while sleeping.
