The ergoPouch Organic Sheet Sleep Bag is the ideal sleeping bag for little ones with allergies or sensitive skin. It is a unique cross between a baby blanket and a traditional baby sleeping bag. It has the softness and fabric weight of a traditional baby blanket, but the construction and comfort of a baby sleeping bag. ergoPouch sleeping bags are all highly breathable, keeping babies warm yet allowing them to keep a consistent body temperature and not overheat. This absolutely gorgeous sleeping bag for Autumn and Summer is suitable for rooms at approx. 21-24 degrees. Using only the finest materials, the ergoPouch is highly breathable, safe and has a 400+ thread count. ergoPouch bags have a slimline fit and special stretch cotton inserts in the shoulders and sides, which allow the baby to move freely and reduce entanglement. The clever 2-way zipper offers easy closure when putting your wriggly baby to bed and also gives you easy access for nappy changing.
