The 1-6m (70cm) Veloudoux® Sleep Sleep Sleep Sack, embroidered with the tender characters from the Anna & Milo collection, is ideal for mid-season and keeps baby warm while he sleeps. The absence of a sleeve allows natural ventilation and regulation of body temperature. The "bottom-up" opening makes it easy for baby to change and prevents him from opening it by himself. It has a Puller Zipper for easy opening and closing. The sleeping bag also has snaps to prevent baby from slipping inside. Thanks to the support seams, the padding retains its original strength. Noukie's Tip: when the temperature of the room requires it, it is possible to promote greater ventilation by partially opening the bottom, thanks to the top-to-bottom closure.
